How to Select and Hire React Js Developers for Your Company And React Js Developer Skills?

What qualities should a good React Js Developer possess? And many other similar types of questions are common in the HR recruiting process for React JS developers. Let's go over these concerns in a step-by-step hiring process for a Great ReactJS Developer. And their skills for React js Developer Job Profile.

Website for Freelancers

Screening the candidates

We should sort through the CVs of candidates to find those with the most relevant skills, experience, and qualifications. The procedure should be followed meticulously to ensure that no relevant CVs are overlooked. This can be done both manually and automatically using the software.

A candidate with prior employment and good background experience should be preferred. Some recruiters believe that speaking with references provided by candidates is ineffective because candidates are more likely to choose individuals who have a favorable opinion; however, it is worthwhile to spend the time.

Shortlisting Candidates

The process makes narrowing down your pool of applicants less daunting. It also establishes standards for you and your talent acquisition team to consider when determining who the best candidates to speak with are.

There are a few advantages to practicing recruitment shortlisting. Shortlisting enables recruiting teams to focus their efforts on the most qualified candidates. Creating shortlisting criteria allows recruiters to spend less time sifting through unqualified applicants and more time on qualified candidates.

Identifying Technical Skills

The most important step in hiring React Js Developer is the verification of technical skills. This stage can be broken down into several sections, such as a technical interview and a test. A technical test, such as a scenario-based or case-based test, is very useful in evaluating React Js candidates.

Conducting a Personal Interview

We have many job requirements basis on that we should determine applicant skills experience and personality. It also assists the employer in determining whether an applicant is likely to fit into the corporate culture. Furthermore, preparing for an interview can help clarify the responsibilities of a position.

Job Offer

Job offer letter should include job title, compensation, benefits, and expected start date should all be included in offer letters. The start date is determined by the candidate's availability, but all other factors can be agreed upon ahead of time. This way, we will be able to send the offer as soon as possible to candidates who have moved on to another opportunity.

Make Contact

Once the candidate has accepted the job offer. The final contract, including additional rules and regulations of the company and other governmental authorities, is included in the offer for the candidate to sign.

I wanted to share some Front End practice interview questions, after interviewing and finding it nothing like Leetcode via /r/webdev

I wanted to share some Front End practice interview questions, after interviewing and finding it nothing like Leetcode

I recently spent some time preparing for Front End interviews and found the suggested 'Software Engineer' interview prep pretty lacking: the common advice is to spend most of your time grinding Leetcode and, for Front End interviews, get ready for countless trivia-style questions.

After half a dozen interviews with Bay Area companies, I personally experienced just one Leetcode-style algorithmic question (a pretty basic graph question) and zero FE trivia questions.

My interview experience was roughly: 25% culture fit, 25% system design/experience (e.g. discussing a project I worked on and choices I made), and 50% practical Front End coding.

This also matches my experience as an interviewer at my previous company, where we phased out both algorithmic and trivia questions (in favor of practical FE coding) after finding they were poor indicators of future success.

IMPORTANT NOTE: your experience may vary, especially with companies based in other states or countries!

I feel like there's a huge lack of practice questions suited for practical Front End interviews, so I wanted to share a handful of my favorite Front End coding practice questions (with slight variations) that came up for me. But first, a few tips for getting the most out of these practice questions:

Use codepen.io - I was asked to use this in nearly every interview. Get familiar with the environment: shortcuts, layouts, how to add libraries, etc

Read the question prompt, and think about what clarifying questions you might ask in a real interview (e.g. unclear requirements, edge cases you might need to account for)

Run through the question once with a time limit. After completing, review your approach: what went well, did you get stuck on any specific parts, what could be improved, etc

Complete the question and think about how you could refactor it for readability, extensibility, re-usability, and performance

Come back to the question later and try it again, but this time using a different approach. e.g. vanilla JS vs framework, React class components vs hooks

Front End coding practice questions

Data fetching and visualization

Prompt: retrieve a list of numbers from an endpoint, then plot a histogram showing the frequency of each number in the list. The histogram should have appropriately numbered x and y axes

In the example below, the list contained 24 ones, 17 twos, 30 threes, and so on.

https://preview.redd.it/jvxwpf13i3d51.png?width=1684&format=png&auto=webp&s=18a86709d03fa6885a5afddf0b7133d17524f6fe

Time limit: 40 minutes

Hints

There are three main parts to this question: fetching the data, manipulating the data (i.e. into a format that can be visualized as a histogram), and drawing the histogram. Start by considering at a high-level how each of these will work

After fetching the data, you should have an array of numbers. Think about what format you need the data to be in to make it easier to draw the chart

Consider using reduce to convert your list of numbers to an object of { number: frequency of that number }

How are you going to draw the chart? If you decide to use plain HTML with some styling, think about what the HTML structure will look like (e.g. how will you draw the axis, how will you dynamically size the bars, etc)

Possible extensions

Ensure your histogram displays correctly with extremes, e.g. how does it handle very high frequencies of a single number, what about negative numbers?

Use different colors for each bar in the histogram

Add a button to refetch/regenerate the data (the endpoint will return random numbers each time)

On hovering over a bar in the histogram, change the color and show a label above the bar with the precise value

You may notice that the random.org URL takes query parameters that will change the numbers generated: include a form that will dynamically generate the URL to provide a different set of numbers (e.g. more numbers, min/max value)

​

Image carousel

Prompt: create an image carousel that cycles through images fetched from an endpoint (displaying a new image every 3 seconds), and allows the user to skip to the next/previous image

The example endpoint contains images within the response as follows:

{ data: { children: [ { data: { url_overridden_by_dest: "*.jpg" } }, ... ] } }

Below is a mockup of what the UI should look like (the carousel should be horizontally centered, with at least some top margin):

https://preview.redd.it/48tq1gbbi3d51.png?width=1686&format=png&auto=webp&s=a8addd3473d64361bb1d7d2cd566ee6dd924e3f4

Time limit: 60 minutes

Hints

As with the previous question, start by thinking about what the main parts of this question are and how to tackle them at a high-level: fetching the data, getting the image URLs from the response, displaying an image, automatically cycling through the images, and allowing the user to go forward and back through the images

There are two ways you could start: stub the endpoint and fully build out the component first (e.g. create a static array of image URLs to use for testing), or fetch the data first and then build the component

Make sure that the data fetching and extraction of the image URLs is cleanly separated from the code that displays the interactive carousel component. Ideally, the carousel component itself should just accept an array of image URL strings

Possible extensions

When the user presses next/previous, make sure that the timer resets

After the last image, make sure the image cycles back to the first

Add image selector circles. The highlighted circle should have the same index of the current image, and the user should be able to click on a circle to jump to that image

https://preview.redd.it/7w5jccmdi3d51.png?width=1026&format=png&auto=webp&s=d97550bbb7444a124ce5aaf118c0f16d90cf4469

Allow the user to select from a (static) list of subreddits to change the cycled images

Allow the user to see top images from the day, week, month, year, or all time by dynamically appending a query param to the URL: e.g. https://www.reddit.com/r/aww/top/.json?t=day (or t=week, t=month, t=year, t=all)

​

Snake game

Prompt: Create a Snake game (example) that meets the following requirements:

15x15 grid

Snake should be controlled with cursor keys (or WASD if you prefer)

Snake should start with a length of 3

One apple at a time should appear in a random position on the grid. When collected, it should increase the score by one, increase the snake length by one, and change to another random position

Display a score for how many apples have been collected

If the snake head collides with the rest of the body, the game should end

If the snake head collides with the borders, the game should end

https://preview.redd.it/v2eqcztfi3d51.png?width=594&format=png&auto=webp&s=3bb3c82528158bde1024cd69a2c18a13e61de3eb

Time limit: 60 minutes

Hints

This is a pretty open-ended question with many different approaches (e.g. HTML canvas, vanilla JS with styled DIVs, framework). Think about the tradeoffs of each, and how you can decouple the model (the game state, logic, and main loop) from the view (how you take that state and render it to the screen)

Begin by thinking about how you will represent the game state

One simple way to represent the game state would be: current apple position as {x,y}, snake body as an array of positions [{x,y},{x,y},...], and score as a number

Build the features very incrementally (planning the order in which you'll tackle them), and test constantly. Start by just getting a single square moving around the grid

Possible extensions

When the game is over, display a game over message with the score and allow the user to press space to restart

As well as the current score, display the player's high score (you could also persist this with localStorage

Before the game starts, display an intro message (e.g. game title, controls, high score) and wait for the player to press a key

Consider ways to increase the difficulty over time (or add selectable difficulty modes): increasing the speed of the snake, adding random obstacles

At this point, you have a pretty complete game: congratulations!

​

More questions?

I have a bunch more practice questions, but it takes a little time to rewrite them in such a way as to test the same concepts and be of similar scope, while also being different enough from the original question asked (while I didn't sign any NDAs, I have been on the other side of the interviewing fence and it's frustrating when your exact question appears on Glassdoor).

If even a few people find these practice questions helpful, I'll spend some time writing and sharing more. Also, if anyone knows of a good repository of Front End practice questions then please share!

Are Escape Rooms and Games Great Ways to Test Potential Hires?

Your job candidates have arrived, but you don’t plop them down for a two-hour writing test nor insist they discuss their professional strengths and past career challenges. No, you usher them into a dark room, handcuff them to a bench and insist they work together to flee their—

Escape room!

Because as far as your company is concerned, how the candidates play the game will tell you if they are team players, appreciate different perspectives, delegate authority and communicate well.

Escape rooms, laser tag, glow-in-the-dark miniature golf, board games, capture the flag—all are unorthodox ways that some companies are sizing up job candidates and potential recruits.

Yet while games may sound like a welcome relief from dry interviews and even drier written assessments, skeptics warn that they may be an inexact way to assess an applicant’s strengths and weaknesses and may even lead to legal troubles.

While Not Ubiquitous, Games Have Potential  

The number of companies using games and other unorthodox candidate assessments is probably low, said Gary Swift, managing director of GolfSupport.com, an online golfing-equipment retailer based in the United Kingdom. The popularity of such games, he said, seems to be prevalent at creative companies, such as tech startups.

One study published in March 2018 in the Journal of Nursing Education reported that the University of Nebraska Medical Center created four escape rooms to show how nursing students could use their skills during health care emergencies. In teams of four, the students solved puzzles reflecting patient health scenarios that included depression, asthma in children and injuries from a motor vehicle accident.

“It could potentially just be a fad,” Swift acknowledged, adding that some companies may be turning to these games because they are becoming frustrated “with the traditional recruitment process of sifting through [resumes] and then carrying out interviews and assessments.”

There may be other dynamics driving the use of unorthodox assessment tools.

The need to enhance the job candidate’s experience might be one, said Mike Cox, president of Cox Innovations, a management consultancy in Houston.

“Technology has helped shift the ultimate ‘buying power’ in the recruiting relationship from employer to candidate, at least when dealing with top-tier candidates,” he said.

“Consequently, there is a burden on companies to not only make the candidate’s recruiting experience positive but also unique and memorable.”

Companies may also try to stand out by appearing innovative, cutting-edge and trendy, he said.

Cox senses that some of these unusual assessment techniques “will become proven over time and will gain prominence slowly,” although they are used by only a handful of employers.

“I doubt we will ever reach a point where they are ubiquitous,” Cox continued, “but I can foresee a point when they are common enough to no longer be considered unorthodox.”

[SHRM members-only toolkit: Recruiting Internally and Externally]

Companies Willing to Give Games a Try

GolfSupport.com surveyed 1,456 companies from a variety of industries to find out if they were willing to use games or sports activities to find and assess new talent.

Among its findings:

More than half said they’d consider reviewing candidates using glow-in-the-dark miniature golf, which is played with only the course and the golf ball illuminated by ultraviolet lights.

Almost 3 in 4 would be interested in using laser tag, typically played in dark, tunnellike rooms where each team tries to “tag” members of the opposing team by “shooting” light beams at opponents’ sensors, worn on vests.

About 2 in 3 would consider using a cooperative board game, such as Pandemic, Mysterium or Forbidden Island, in which a team of players works together against the game itself.

The Knowledge Academy, which provides training for professionals, found that of 684 companies and job seekers, large majorities would be willing to use similar games during job interviews.

So how does it work? In general, assessors observe the game and take notes from a distance, typically concluding the activity by asking candidates questions about their experience.

Those interviewed for this article noted that each activity tends to draw out specific skills or strengths. For instance, the board games assess teamwork; laser tag assesses strategy and communication; glow-in-the-dark golf reveals ambition and confidence; and escape rooms measure problem-solving, critical thinking and teamwork. 

The games “are a great way to access a candidate’s soft skills,” Swift said. Candidates’ “soft skills are about the way they carry out essential tasks and their ability to creatively solve problems or work within a team. According to LinkedIn, 92 percent of talent professionals say soft skills matter as much as or more than hard skills when they hire, and 80 percent say they’re increasingly important to company success.”

The Drawbacks

An unconventional approach to interviewing, recruiting or assessing candidates may serve some purposes, said Keith Wolf, managing director of Murray Resources, a Houston-based recruiting and staffing firm.

“If being able to participate and enjoy a series of games is essential to jelling with the team because they’re all Frisbee golf fanatics, then it could make sense,” he said. “However, your best accounting candidate may be brilliant and just what your team needs, but too introverted to enjoy a game of tag with a group of strangers.”

Cox agreed that there may be instances when games and sports say something about a candidate.

“How somebody reacts to having their ideas unfairly challenged is valuable information for anybody who is going to be asked to operate in a team,” Cox said. “Traditional interviewing would likely ask the candidate to provide an example of when this happened in the past and how they handled it. While this is helpful, its usefulness is … subject to the candidate selecting an inherently positive and not necessarily representative example.

“However, if that same individual’s behavior in such a situation was observed within a game, the company would likely be receiving much more useful, authentic information.”

Cox noted that games should complement traditional interviewing techniques, not replace them. Moreover, he cautioned, companies can run legal risks when using games to assess job candidates.

“The most common risk is that an employer gets accused of making a hiring decision that indirectly is driven by a protected attribute. For example, an activity that involves significant physical exertion could expose an employer to claims that the activity enabled discrimination based on age or disability.” 

//window.fbAsyncInit = function() { FB.init({ appId: '649819231827420', xfbml: true, version: 'v2.5' }); };

//(function(d, s, id){ // var js, fjs = d.getElementsByTagName(s)[0]; // if (d.getElementById(id)) {return;} // js = d.createElement(s); js.id = id; // js.src = "http://connect.facebook.net/en_US/sdk.js"; // fjs.parentNode.insertBefore(js, fjs); //}(document, 'script', 'facebook-jssdk')); function shrm_encodeURI(s) { return encodeURIComponent(s); } function RightsLinkPopUp() { var url = "https://s100.copyright.com/AppDispatchServlet"; var location = url + "?publisherName=" + shrm_encodeURI("shrm") + "&publication=" + shrm_encodeURI("Legal_Issues") + "&title=" + shrm_encodeURI("Justices Hear ERISA Reimbursement Case") + "&publicationDate=" + shrm_encodeURI("11/11/2015 12:00:00 AM") + "&contentID=" + shrm_encodeURI("6badda72-62e7-49e8-b4bd-ebbd02a72a17") + "&charCnt=" + shrm_encodeURI("7399") + "&orderBeanReset=" + shrm_encodeURI("True"); window.open(location, "RightsLink", "location=no,toolbar=no,directories=no,status=no,menubar=no,scrollbars=yes,resizable=yes,width=650,height=550"); } Source link

How to Hire a Great React Native Developer

This post is originally posted in Toptal. React Native is a library for rendering mobile applications on iOS, Android, and UWP. Using React Native, it’s possible (in most cases) to write code once and deploy to all available target platforms—which is probably why you’re looking to hire a React Native developer. React Native shares many concepts and libraries with React, so it’s important for any React Native job that the developer is at least familiar with React on the web and its common patterns. It’s also recommended that a React Native developer is proficient with JavaScript and especially with the ES6 syntax. Many of the questions in our React hiring guide apply when hiring a React Native developer as well, so it is better to keep both guides in mind at the time of interview. Of course, the JavaScript hiring guide also applies: As the guide mentions, there’s a big difference between having some understanding of JavaScript and being an expert in it, and being a JavaScript expert is paramount when working on React and React Native jobs.

React Native Interview Questions

Let’s dive into some React Native interview questions to help you in the process of assessing your candidate. What are React Native components? Components are the building blocks of a React Native application. React Native provides a set of components that map to the corresponding native components on each platform which the React Native developer can use. Some components can be used on all platforms (like View, Button, and FlatList) while others are platform-specific, as they map to native components that exist only on iOS or Android: For example, iOS does not have a hardware back button, so a BackHandler component for iOS would not make sense. The developer can create their own component by extending the React.Component class, and implementing the Render method: export default class App extends React.Component { render() { return ( // my component's visual tree ); } } What’s the best way to display items in a list, performance-wise? React Native offers a VirtualizedList component that provides virtualization out of the box. While VirtualizedList can be used directly, the more high-level FlatList (display items in a scrollable list) and SectionList (same as FlatList but with grouping and custom sections) implementations are fit for most use cases. Some things are important to keep in mind when working with a VirtualizedList, however. There’s no assurance that the internal state of the items in the list will be kept when scrolling the list: Based on the amount of elements and the level of scrolling, the list might dispose of some elements outside of the viewport. Those elements will be recreated from scratch based on props when coming back into the viewport. So, the developer needs to make sure that the item can be recreated based on props alone. Items should specify a Key property which identifies them uniquely. Alternatively, it’s possible to provide a custom KeyExtractor in the list’s definition: It’s a good practice to make sure list items do not re-render if passed in the same props they already have. This can be accomplished by implementing shouldComponentUpdate in the item’s component, or alternatively inherit from the React.PureComponent class, which provides an implementation of shouldComponentUpdate that does shallow prop and state comparison. How do you style components in React Native? Styling is specified by plain JavaScript objects, and all React Native components accept a Style prop that can be set with the object specifying the style. Note that while the syntax resembles CSS, it’s not CSS, and styling a React Native application’s components does not follow the same conventions. Notably, all properties follow the camelCase convention instead of dash-case (background-color becomes backgroundColor) and layout can be specified only using the Flexbox algorithm. Since style definitions are done in code, it is easy to parametrize styles and do things that usually CSS preprocessors/extensions (Less, Sass) are used for: import { StyleSheet } from 'react-native'; import { primaryColor, secondaryColor } from './style/consts'; // values defined in another .js file let width = 50; ///... const style = StyleSheet.create({ 'color': primaryColor, 'backgroundColor': secondaryColor, 'width': width }); How would you debug a React Native application? While running a React Native application in the emulator, it’s possible to access the developer menu by either “shaking” the device (by selecting the “shake” gesture in the emulator) or by pressing Command-D (iOS) or Control/Command-M (Android). The developer menu will display a “enable JS debugging” menu entry, among other things. After clicking it, it will be possible to browse to http://localhost:8081/debugger-ui with Chrome/Chromium, which displays the debugger. Log traces are visible by running react-native log-android for Android, and react-native log-ios for iOS, while the emulator is up. If using Redux, Reactotron is especially useful to see all API calls and actions dispatched. Our existing codebase is in Xamarin, and you would be helping to port it to React Native. What would be the issues to watch for? Unlike our other React Native interview questions, this may not apply to every project. But if it does, it’s certainly an important line of questioning to consider. React Native and Xamarin.Forms adopt the same approach towards making cross-platform applications: Both take a UI definition (virtual DOM or XAML) and transform it to native code. There are two main differences between the two: The language of choice: It’s almost always C# for Xamarin—though potentially any other language available for the .NET framework—and JavaScript for React Native. The development platforms they’re available on: React Native is available for Linux, MacOS, and Windows, while Xamarin is officially available only on Windows and MacOS. While React Native and Xamarin.Forms do conceptually the same thing, the abstractions they use are not directly compatible. For example, a component available on React Native might not necessarily be available on Xamarin, and vice versa. Also, the same abstraction is often implemented in different ways across the two frameworks: Take FlatList and SectionList on React Native, which map to their corresponding concept on both iOS and Android, and ListView on Xamarin.Forms, which conflates the two into one single UI component. If a React Native developer were to tackle a port from Xamarin.Forms, it would be greatly beneficial for them to have at least some experience with C#, and ideally some experience with Xamarin. What’s the relationship between React and React Native? React is a JavaScript library that allows the developer to define a user interface in a declarative way. If offers some infrastructure when it comes to state handling (props for one-way data flow, injected from the outside; state for two-way data flow, internally managed state) and general component lifecycle method hooks. React keeps in memory an internal representation of the UI (virtual DOM). It uses this representation to compute deltas in the visual appearance of the components on props/state changes, in order to make it possible to partially update the UI on data changes—thus avoiding the need for complete redraws. React Native sits on top of React and, where React would render the virtual DOM as an HTML document, React Native maps the virtual DOM to native iOS/Android components. So, while React is often used together with JSX in order to generate HTML output, React Native has its own set of tags that represent abstractions of native components. Those native components are what get displayed on the device in the end. So, if a React component would look like the following: class ReactJSComponent extends React.Component { render() { return( Hello world! ); } } …then an equivalent React Native component could be something like: class ReactNativeComponent extends React.Component { //note that's the same class we're extending render() { return( Hello world! ); } } Libraries that are often use to handle state (Redux, MobX) and most plugins that are not dependent on UI are used the exact same way in React and React Native, and most patterns/best practices that apply to React apply to React Native too. Highlight the major differences and tradeoffs between native development and mobile development using React Native. React Native has clear benefits when it comes to mobile application development: React Native allows for cross-platform development: The application logic is written once, using the same language (JavaScript) and can be deployed to the available target platforms (iOS, Android, and UWP). Writing an application natively for a specific platform requires instead an almost complete rewrite when porting said application to a different platform. A React Native app, with some limitations (see below), is written in JavaScript. That can be a plus or a minus depending on the situation, but generally, finding developers that are experienced with JavaScript is not as hard as for other languages. Hot reloading is a great React Native feature, allowing the developer to change the application code and see those changes directly in the emulator, with no need for recompiling/redeploying. React Native is a strong choice, especially considering the ever-increasing user base and continuous improvements made to it. But there are some drawbacks to be considered: While performance has been improving steadily over the last two years, React Native is still significantly slower than a visually equivalent native application, especially when the application makes heavy use of animations or has a complex UI. Some native functionality is not available for use directly from React Native, and it might be necessary to write modules for each target platform, in the target platform’s language. JavaScript is a mainstream language and thus widely known and used, but it has some serious drawbacks. It might be challenging to write and maintain a JavaScript application that scales up to a certain size. How does React Native behave across different platforms? React Native takes the virtual DOM, generated by React based on the interface definition—i.e. the result gotten from calling the render method on the application’s components. It then uses this to generate native code for each of the target platforms. That means that, for the most part, the developer doesn’t have to worry about platform-specific details and can rely on React Native outputting the right native code based on the situation. For example, if the developer adds a Text component, it will be transformed into a UITextField on iOS, and into a TextView on Android. The same goes for layout definitions: React Native uses flexbox, and that is translated as proper layout definitions specific to the target platform when the application is deployed. Sometimes the abstraction provided by React Native is available only on some of the target platforms (an example would be the already-mentioned BackHandler). When that’s the case, it is up to the developer to properly make use of the abstraction. A check for the current platform might be necessary: import {Platform} from 'react-native'; if (Platform.OS == 'ios') { // iOS-specific code } There are some cases where React Native does not provide an abstraction layer over native components or functionalities. In those cases, the developer will have to write a native module, in the target platform’s language. That is done by extending the ReactContextBaseJavaModule for Android, and by implementing the RCTBridgeModule in iOS. With those modules in place, it’s possible to interact with them from React Native using the endpoints explicitly provided by the modules themselves. We simply annotate methods with @ReactMethod on Android and by exporting classes and methods with RCT_EXPORT_MODULE and RCT_EXPORT_METHOD on iOS: public class MyModule extends ReactContextBaseJavaModule { @ReactMethod public void myMethod() { // implementation } } @implementation MyModule RCT_EXPORT_MODULE(); RCT_EXPORT_METHOD(myMethod) { // implementation } import {NativeModules} from 'react-native'; // call it like this: NativeModules.MyModule.myMethod(); What are the different options available when it comes to handling state in React Native? As it is, React (and thus React Native) does not enforce any kind of global state management. The only patterns available to use for the developer are injecting state into components using props, which are meant to be immutable, and internal component state managed privately through the state property. There are several options available when it comes to global state management, the more widely used being Redux. If the developer is familiar with Redux on React, there are no changes for when it comes to using it on React Native. The behavior is exactly the same, as are the common patterns of use. Another available option to manage global state is MobX, which handles state using observables and bindings, the way Knockout.js and WPF do. While Redux follows functional programming paradigms—and is suited to that kind of programming style, for that reason—MobX can be easier to pick up for those coming from an object-oriented background. Both options are valid, and it’s important to consider the team’s composition before picking one or the other. Redux is often the choice preferred by those with a functional programming background, but it can be challenging to get up to speed with. MobX offers a flatter learning curve, but it might show problems when the application grows up to a certain size. What is a Thunk? Generally speaking, a Thunk is a function returned by another function. It is used to defer computing a result to when the result is actually needed: function doMyThing() { return function() { return "my result"; } } The concept is important for the React (and React Native) developer because they’re used in one of the most popular pieces of middleware for Redux: redux-thunk. That allows React actions, which are normally just plain JavaScript objects, like this: { type: "MY_ACTION_TYPE", value: "myvalue" } …to actually dispatch other actions directly, like so: function myActionCreator() { return function(dispatch, state) { dispatch(anotherActionCreator()); } } There are other pieces of middleware for Redux that do not expose the concept directly—the most famous being React Saga—but it’s very important that your React Native developer candidate is comfortable with functional programming concepts like the above. What is middleware? How is it used in Redux? Redux middleware is a function provided to Redux by the developer (either imported from an external module, or developed directly) that intercepts all actions dispatched before they reach the reducers, potentially does some operations on those actions, and forwards them to the reducers afterwards. Middleware thus provides a hook that can be used to run custom operations on actions before they reach the reducers. This is important, as many libraries and extensions (e.g., the aforementioned redux-thunk) register themselves as middleware. A piece of middleware returns a Thunk, as it is a function that returns a function. A sample middleware implementation looks like this: // middleware that does nothing const myMiddleware = store => next => action => { return next(action); } Here, store is the application’s store, available from inside the middleware function. That means that store.dispatch is available from inside the middleware, thus making it possible to dispatch more than one action per action received—beware of infinite loops! Then next is a function that returns a function (which will dispatch the action) and expects an action as the parameter. The above middleware can be registered using the following: const store = createStore( myCombinedReducers, applyMiddleware(myMiddleware, otherMiddleware) )

Gauging Your React Native Developer Candidate

The answers to these questions should give you an idea of how much a developer candidate is comfortable working with React Native. This hiring guide, of course, was not meant to cover an exhaustive interview, but to act as a guideline—there’s much more both to React Native development and to app development in general. For example, somebody who is very experienced with both JavaScript and React should be able to pick up React Native and its concepts in no time. At the same time, someone who has been working a bit with React Native development but does not have extensive experience with JavaScript or with native development might know the answers to the questions above, but not be very effective as a React Native developer. Your mileage may vary, as with everything else in life. Good luck! Read the full article

Ensure you assess browser support! http://bit.ly/2kA8ySD Previously it had been done with the guidance of cookies. If you're searching for work that's related to CSS you want to get ready for your 2019 CSS Interview Questions. https://tinyurl.com/y5bylwsn Ask your interview is filmed so you can be critiqued by them and you may study the film. In general, you should expect a great deal of your interviews to become functional as well as somewhat coding. It's a simple fact that every interview is different based on the job profiles. A job interview may be an dance. HTML layout specifies a manner. Utilize sprite images whenever it's possible, attempt to set pictures utilized in 1 file to be requested once. A view is a table that's composed of a subset of all information. You can create your own thing. Utilizing box model it can help to align with the HTML components. The details tag is utilized to specify some additional details on the online page. Each HTML tags have properties. AJAX is best suited for small (hopefully unobtrusive) updates to the present webpage, determined by information that isn't accessible until it has been provided by the end user. Javascript cannot operate by itself. JavaScript must be known by you and you wish to know it inside out. Javascript has a method of hoisting variable declarations to the peak of the function. CSS is referred to as a Cascading style sheet. CSS floats are common and therefore is the difficulty related to the collapse of floats. Pages load faster If you're using CSS, then you do not have to compose HTML tag attributes every moment. In the last few decades, browsers have come a long way. Users will have to enable and install flash plugin in their browsers. They may be redirected to a different URL once a website has been opened coded in JavaScript. You just have a look. Let's take a glance at what skills you should start looking for in an AngularJS developer and in the event that you wish to leave professionals items it's possible to utilize our Angular JS Online Test before jumping from the queries. Knows the response to A Knows the Answer to D and A Knows the Answer to A, B and D Knows the response to C too! There are tons of ways. The notion here is to not go through the queries and look for the answer. The idea of CSS sprites is utilised to reduce the loading time to get an internet page for the reason that it unites the various little images into a single picture. Let us look at each area of the answer separately. Your answers permit the interviewer to get an idea about understanding that is practical and your skills. Excellent answers might be that sprites are often for icons and icons frequently don't need to be raster when inquiring about alternatives. It's far better have canned responses. https://is.gd/CsK5fg Please discuss any other Spring excellent MVC interview questions you may have confronted. What's more, it helps remove programming problems using static investigation. https://annuaire-du-net.com/javascript-interview-questions-and-answers/ Once you have built a couple sites that are responsive you can worry about the issues of media. Your design decisions end being made by somebody else who's never seen that your own endeavor. The procedure is known as linking the tables. Odds are that React could be a fit for you, if you're seeking to construct a strong web program. Despite the fact that the frame supports Dart and JavaScript, the contender for absolutely any new development that is possible appears to be Typescript. It needs a minimum of Java 8. Now, if you announce walk() method in the Individual category, you will wind up recreating the method for each new example of Person. HandlerInterceptorAdapter class can be utilized by you to steer clear of overriding. You need to produce a course and implement Validator interface. You are able to use modifier course or an class rather than an ID if you will have to target a product. You are able to also say responsive UI design is just Liquid layout's advanced degree. The absolute most prosperous interview answers concentrate on the hiring manager's needs. Get the information that you need! If you discover anything incorrect, please publish comments, or you would like to share info about the topic mentioned previously. Depending on the client browser the internet webpage will adjust automatically. Every site has a specific layout to display content in a way that is certain. Broadly speaking is ask a source. With the guidance of alterations in CSS code, you are ready to alter the way that your site appears. Where it's likely to pick up the basics there are tons of resources online.
