Let's talk about filtering and mapping! 🤓

I'm working on the menu page for a restaurant, and as someone with very little frontend experience I wasn't sure how to go about parsing through a JSON file to return certain objects.

After some searching, procrastinating, going through this course, and then more searching - I finally came across the documentation I needed here!

So what is filtering and mapping? .filter() and .map() are JavaScript methods.

filter allows you to filter through an array of objects given some logic (want to find all the items with an id greater than 7? filter. Want to find all the items where the name is equal to "burger" that works too, want to add multiple conditions to find all the items with and id greater than 7 AND the name is "burger" well filter has got your back).

map is used to iterate through an array and call a function on every element in it. I used it to map each item to a list.

Here's an example: We have a JSON file of some food items.

We want to grab all the desserts from our menu and display them on the desserts page of our website. It's time to filter!

Keep in mind that the filter method returns a new array with all the objects that we want. In this case when we filter we will get an array with all the desserts.

First we import our JSON file so we can access it.

Next, we create a constant called dessertFilter which will hold our filtered array. dessertFilter will hold all items that have the type equal to dessert. In our example it will hold the chocolate cake object.

Next, we map each item from the new array to a list. This is the list that we'll see displayed on the page. You can choose which properties you want to map. We only map the name, description and price since there's no need for the user to see the item type or id.

Lastly, our return statement contains everything we will see on the page. In our return we have a header and the list of items - we wrap our list, dessertItems in an unordered list since list items need to be wrapped in either an ordered or unordered list.

Here's our result! We can style this with css later.

Cool! so we filtered for dessert but what about our other menu items? Time to make a reusable component.

The code is almost the same, but to make this component reusable we create an interface. Interfaces define objects and specify their properties. We specify an object called filterSearch that will act as a placeholder - we set it as a string since the item "types" in our JSON file are strings. (I'm using typescript which accepts interfaces but i believe vanilla javascript does not).

Now lets see the component in action

Import the component so we can call it.

When we call FilterMenu we have to include filterSearch from our interface. The component needs to know what we're looking for. Here we can set it to any valid type like "dessert", "drink", or "appetizer" and it will display them.

Woo! now we're filtering and mapping with one line of code! and we can reuse it for our other pages too.

Last thing, these methods are chainable! you can connect them and have the same logic in one constant.

Before reading the documentation, I had seperate JSON files for each menu category and was reusing the same code to map each file on each individual menu page. It was a lot of duplicate code, not great. Now, I have a single JSON file and a reusable component. It's satisying how clean it is!

Learning on your own can be frustrating sometimes, it can be hard to search for solutions when you don't know where to begin. I had never heard of filtering or mapping before this. If you're ever stuck keep pushing! there's so many resources and communities out there.

p.s. I'm open to any suggestions!

Quote of the Week

In [other languages], I could end up chasing silly bugs and waste time debugging and tracing to find that I made a typo or ran into a language quirk that gave me an unexpected nil pointer. That situation is almost non-existent in Rust, it's just me and the problem. Rust is honest and upfront about its quirks and will yell at you about it before you have a hard to find bug in production.

Learning TypeScript for Safe Programming

TypeScript is a superset of JavaScript that adds static typing to the language, making it a powerful tool for building robust and maintainable applications. By catching errors at compile time rather than at runtime, TypeScript helps developers create safer and more predictable code. This post explores the fundamentals of TypeScript and how it can improve your JavaScript development experience.

What is TypeScript?

TypeScript is an open-source programming language developed by Microsoft. It builds on JavaScript by adding optional static types, interfaces, and advanced tooling. TypeScript code is transpiled into plain JavaScript, allowing it to run in any environment where JavaScript does.

Why Use TypeScript?

Static Typing: Identify type-related errors at compile time, reducing runtime errors.

Improved Readability: Types serve as documentation, making code easier to understand.

Enhanced Tooling: Better autocompletion, navigation, and refactoring support in IDEs.

Large-Scale Applications: Facilitates building and maintaining complex applications with better structure.

Community Support: Growing ecosystem and support from popular libraries and frameworks.

Getting Started with TypeScript

Installation: You can install TypeScript using npm:

Compile TypeScript: Use the TypeScript compiler (tsc) to transpile .ts files into .js files.

Configuration: Create a tsconfig.json file to customize your TypeScript project settings.

Basic Types in TypeScript

TypeScript supports various data types, including:

Primitive Types: string, number, boolean, null, undefined, void, symbol.

Arrays: Use the syntax number[] or Array.

Tuples: Define an array with fixed number and types of elements.

Enums: Create a set of named constants for better readability.enum Direction { Up, Down, Left, Right }

Interfaces and Type Aliases

Interfaces allow you to define custom types for objects, promoting better type safety:interface User { name: string; age: number; } const user: User = { name: 'Alice', age: 30 };

Classes and Inheritance

TypeScript supports object-oriented programming with classes and inheritance:class Animal { constructor(public name: string) {} move() { console.log(`${this.name} moves.`); } } class Dog extends Animal { bark() { console.log('Woof! Woof!'); } } const dog = new Dog('Buddy'); dog.move(); // Buddy moves. dog.bark(); // Woof! Woof!

Best Practices for TypeScript Development

Always define types for function parameters and return values.

Use interfaces and types to enforce consistency in data structures.

Utilize TypeScript’s strict mode for better type-checking.

Regularly update your TypeScript version to take advantage of new features.

Conclusion

Learning TypeScript is a valuable investment for any JavaScript developer. By incorporating static typing and leveraging TypeScript's advanced features, you can create safer, more maintainable, and scalable applications. Start experimenting with TypeScript in your next project, and enjoy the benefits of safer programming!

A Comprehensive Guide to Angular Data Binding for Seamless Capabilities 

Modern apps demand consistency in the components, state, and features. In complex business apps, Angular data binding plays the role of cornerstone. The process keeps the model and components in sync. So, this offers a streamlined view of the data interaction in the app. Plus, it helps to manage complex apps efficiently. But if this process confuses you, then let's dive in to understand its benefits. 

What is data binding in Angular? 

Angular data binding maintains the synchronization between the data model and the app view. This process allows us to dynamically link the TypeScript component to the HTML elements. It ensures that the UI updates in real-time for reacting to events or working with data. 

Consider a situation when a user enters text in a form field. Any changes made to the text get reflected in the app's underlying data model. The dynamic interaction improves efficiency and reduces DOM changes. 

Types of data binding in Angular 

Here are the primary types of data binding in Angular apps. 

Property binding 

This Angular data binding enables to set of values for Angular directives, DOM properties, and HTML attributes. The data moves from the component to the view because it is a one-way data-binding. You can use a component property to modify an element's styling. Making templates dynamic to changes in the app state is the main benefit. The property binding modifies text content for user actions and toggle visibility. 

Class binding 

A way to dynamically add or remove CSS classes from HTML elements. When styling items according to specific states or conditions, this is quite helpful. You can bind a single class to a Boolean property so that the class evaluates to true. Class binding can be used to show error messages to highlight an active menu item. More complicated class-binding scenarios include applying to many classes. Or even it at once via arrays or objects, get supported by Angular. You can get an AngularJS web development company for more assistance. Because of its versatility, it's a useful tool for controlling your app's presentation layer. 

Event binding 

Event binding links function in your component to user actions like clicks. This enables the proper logic to be executed by your program in response to user input. You can use event binding to run a function whenever it gets an action. The event wrapped gets followed by the method to run in Angular's user-friendly event. Because this Angular data binding offers communication between the logic and the UI. Plus, event binding is crucial for developing interactive apps. 

Two-way binding 

Property and event binding are combined to provide two-way binding. It makes it easy for the view and the component to synchronize in real time. Any adjustments to the property are in the view, and changes made to the input are in the component. The ngModel directive in Angular is used to accomplish this. Plus, making it easier to connect form controls to component properties. When creating forms, search bars, and interactive elements that get updated often. 

Advantages of Angular data binding for businesses 

Here are some benefits of using data binding in Angular. 

Efficiency: Eliminates the need for manual DOM manipulation, resulting in less boilerplate code and fewer errors. 

Reactivity: Keeps the UI and application logic in sync, which improves the user experience. 

Scalability: It is easier to manage complex apps with dynamic components and interactive elements. 

Readability: By isolating the presentation layer from the application logic, the code becomes easier to maintain. 

Best practices for effective Angular data binding 

Let's look at the numerous practices for effective data banding process. 

Keep components modular 

Modularize your program into discrete, reusable components for better readability and maintainability. 

Avoid overuse of two-way binding. 

Avoid overusing two-way Angular data binding, as it can cause performance bottlenecks.  

Use typeScript strictly: 

Use TypeScript conventions to ensure type safety in your components. This reduces runtime errors. 

Minimize DOM manipulations 

With the reduction of DOM manipulation, you decrease manual interventions. Use Angular bindings for DOM updates instead of direct manipulation. 

Conclusion:  

Angular data binding holds crucial importance in maintaining Angular functionalities. And the developers can build dynamic and interactive applications. Also, it helps to create a user interface that reacts to changes simultaneously. Plus, an AngularJS Web Development Company can also help you in the binding process.

Documentário sobre JavaScript Básico

Fala meus DEVs lindos (2 pessoas que seguem a página) durante minha jornada de Front-End eu me encanei bastante com o querido JavaScript em meus projetos, seja chat-bot, to do list ou qualquer mínima aplicação.

Atualmente eu tenho o objetivo de migrar para o TypeScript, PORÉM, não é tão simples refinar para o TS sem aprender o JS primeiro na minha opinião, sendo assim eu me enfiei em alguns cursos e quero gravar um FaaF Archive lá no canal desvendando um pouco das experiências que eu tive com o JavaScript que vou relatar um pouco aqui no BLOG.

Vamos começar falando do porque eu acho que tem tanta gente que prefere o PYTHON a mexer no JavaScript, isso porque o PYTHON É UMA MÃE CARINHOSA perto da paulada que você vai encontrar aqui. Estamos falando de uma linguagem de programação que vai somar um Number com uma String! E tirando essas esquisitices de lógica de comparação, eu não encontrei dificuldade alguma com Variáveis, Elementos, condicionais e Fluxo de execução. Sem dúvida se você já possui uma lógica de programação na cabeça, vai ser uma questão de adaptação para você aprender a mexer no básico do JavaScript.

Uma das experiências mais legais que eu aprendi ao começar a programar em JavaScript foi a parte de Debbuger do VSCode, ele serve para indicar para você basicamente "Em que ponto paramos" assim que ele atingir uma linha de código que você indicou, fazendo ele parar ali e procurar entender o que tá rolando. Vou mostrar um exemplo:

Você está com um código em Loop dentro de um While e precisa saber se um item específico está dentro de uma lista, assim o código vai ficar em Loop até encontrar o que você quer. Primeiro passo é criar um "contador" e considerar que ele é menor que o número de itens na sua lista para ele verificar um por um.

Pega seu valor e soma 1 nele mesmo

Nesse exemplo de código abaixo ele vai verificar se há um destino em um Array de destinos:

Esses são os BreakPoints:

Assim, quando for Debbugar, o código vai parar nesses pontos

Assim você consegue verificar exatamente o que está acontecendo com o isso código, ou é claro, você pode ser RAIZ e meter uma série de console.log() e ver o que está acontecendo.

Meu último tópico sobre o JavaScript Básico o que eu tenho a comentar é que eu prefiro muito mais a estrutura do While do que do FOR, apesar de serem semelhantes existe uma mudança clara na estrutura do código.

Enquanto no While você insere a condição dentro do parênteses, no FOR você precisa colocar o valor da variável, sua condição e o que deve ser executado, tudo logo de cara e sem choro.

Enfim pessoal, eu dei uma geral simples sobre o JavaScript básico e tenho muito mais a comentar sobre a Programação Orientada a Objetos do JavaScript, se quiserem que eu faça uma parte 2 desse comentário basta pedir e se quiserem podem acompanhar o desenrolar dessa saga lá no Youtube: FaaF Archive!

[hyperoperationfractallisation]

Why is typescript being so annoying. I just want to be able to pass an item or array of items into the function. Why do you have to be so pissy about types. Why can't I just say "if it is an array, do this". I can't even ask it "is this an array". I hate it.

Matt Pocock's Total TypeScript: Essentials

Some notes I made while reading this book:

Optional values in a tuple

Not only can a tuple have named values, it can have optional ones:

[name: string, year: number, info?: string]

[string, number, string?]

Dealing with an unknown

If we have obj of type unknown, and we want to get obj.prop of type string, this is how to do it correctly:

typeof obj === 'object' && obj && 'prop' in obj && typeof obj.prop === 'string'

If we refactor the expression above into a return value of a type guard, this would be its type signature:

(obj: unknown) => obj is {prop: string}

Destructuring values of union types (tuples vs. objects)

const [status, value]: ['success', User[]] | ['error', string] = await fetchData();

TS can then guess based on the type of the discriminant (the status variable) the type of the rest of the return value (the value variable), but wouldn't be able to do the same, if fetchData returned an object instead of tuple. An object type should be narrowed first, before we can destructure its value!

Dynamic keys

If we don't know, what keys the object may have during the lifetime of the program, we can have index signatures...

type DynamicKeys = { [index: string]: number; }

interface DynamicKeys { [index: string]: string; }

...or we can use Record helper type. Record type supports union types of type literals, unlike index signatures!

type DynamicKeys = Record<'name' | 'age' | 'occupation', boolean>

Read-only arrays

We can disallow array mutation by marking arrays and tuples as readonly, or using ReadonlyArray helper type:

const readOnlyGenres: readonly string[] = ["rock", "pop", "unclassifiable"];

const readOnlyGenres: ReadonlyArray<string> = ["rock", "pop", "unclassifiable"];

Read-only arrays/tuples can only be passed to functions that explicitly expect read-only arrays/tuples:

Matt's strange opinions on class methods

function printGenresReadOnly(genres: readonly string[]) { }

More helper types

When Matt talks about the difference between arrow and function methods, he mentions only the different ways they handle this, but isn't a much more important distinction the fact that arrow methods are technically class properties, so will be copied on every instance of a class?

UPD: And later he recommends using arrow functions!

This is extremely memory inefficient, right?

satisfies operator

Very useful thing I've never heard of before!

When a value isn't annotated with type, its type is inferred. When a value is annotated with type, its type is checked against the annotated type. When a value is followed with satisfies, its type is inferred (as if there were no annotation), but still checked against the constraint (as if there were an annotation).

Useful (?) type assertions

as any // turns off type checking for a particular value.

as unknown as T // cast a value to a completely unrelated type.

as const satisfies T // makes a value immutable, while checking it against a type.

Object.keys (user).forEach((key) => { console.log(user[key as keyof typeof user]); }) // by default TS infers return values of Object.keys() and for ... in as string[].

Excess properties

TS doesn't throw an error, when (1) a variable containing an object with excess properties is passed to a function, or (2) when an object with excess properties is returned by a callback. Both the variable and the return type of the callback should be annotated, if that is an issue.

Modules vs. scripts

Files with no import or export statement are treated by the compiler as scripts, executing in the global scope. The problem is, that's not how the distinction works in pure JS, so we can end up in sitiations like this...

...just because the name variable already exists elsewhere. One way to fix this mistake (which I knew about) is by adding export {}; to the end of the file, turning it into a module from TS perspective. Another way (which I found out about just now) is by adding line "moduleDetection": "force" to the config file. Cool.
