Enable, Execute, Expect

Much ink has been spilled (metaphorically) around the topic of writing good unit tests. One of the best patterns I've seen for thinking about how to write good unit tests is the Arrange-Act-Assert pattern, also known as Triple AAA tests. Here's a selection of articles illustrating this pattern:

The Automation Panda's Take on AAA tests

Jay Cruz and the Three A's of Unit Testing on Dev.to

Leaning unit testing from Microsoft

and so on.

The gist is that every unit test should have three parts: arrange your test with fixtures and elements to test, perform an act on these fixtures that you wish to test, and then assert the actual result of the action is the same as you expect.

This is a great pattern, except for one tiny issue: in some languages, there isn't really an "assert".

Increasingly, instead of the syntax

assert expectedCondition == actualCondition

we see something like

expect(expectedCondition).toBe(actualCondition)

This is true in JavaScript/TypeScript world, as well as in the Ruby world. In JS you have this pattern in libraries like Jest, while in Ruby the RSpec framework uses expect as well. This could lead to developers who never actually use an assert keyword in code. This leads the Triple AAA mnemonic to shambles.

Hence, here is the recipe Triple EEE tests:

Enable test fixtures as needed

Execute a step to be tested

Expect a result and verify this happens.

A nice acronym, exactly expected.

A structured way to learn JavaScript.

I came across a post on Twitter that I thought would be helpful to share with those who are struggling to find a structured way to learn Javascript on their own. Personally, I wish I had access to this information when I first started learning in January. However, I am grateful for my learning journey so far, as I have covered most topics, albeit in a less structured manner.

N/B: Not everyone learns in the same way; it's important to find what works for you. This is a guide, not a rulebook.

EASY

What is JavaScript and its role in web development?

Brief history and evolution of JavaScript.

Basic syntax and structure of JavaScript code.

Understanding variables, constants, and their declaration.

Data types: numbers, strings, boolean, and null/undefined.

Arithmetic, assignment, comparison, and logical operators.

Combining operators to create expressions.

Conditional statements (if, else if, else) for decision making.

Loops (for, while) for repetitive tasks. - Switch statements for multiple conditional cases.

MEDIUM

Defining functions, including parameters and return values.

Function scope, closures, and their practical applications.

Creating and manipulating arrays.

Working with objects, properties, and methods.

Iterating through arrays and objects.Understanding the Document Object Model (DOM).

Selecting and modifying HTML elements with JavaScript.Handling events (click, submit, etc.) with event listeners.

Using try-catch blocks to handle exceptions.

Common error types and debugging techniques.

HARD

Callback functions and their limitations.

Dealing with asynchronous operations, such as AJAX requests.

Promises for handling asynchronous operations.

Async/await for cleaner asynchronous code.

Arrow functions for concise function syntax.

Template literals for flexible string interpolation.

Destructuring for unpacking values from arrays and objects.

Spread/rest operators.

Design Patterns.

Writing unit tests with testing frameworks.

Code optimization techniques.

That's it I guess!

[akaicodes]

update to my roadmap of learning https://www.tumblr.com/akaicodes/744920785897111552/roadmap-of-learning-curriculum-related-so-far - 4 months later ♡

• C# - spent ~1 year so far practicing, more comfortable, can build whole sites/programs with little help

• HTML & CSS - started ~5 months ago, confident in both, can style a site without help online, still much to learn

• JavaScript + Vue - Axios - can build “full stack” applications where i do both backend & frontend and host online (love JS!!)

• REST - experienced for 5 months! can build my own REST API, use someone elses with axios & test it thoughoutly with Postman (+Javascript code)

• Unit testing & UI testing - learned so many better ways to unit test & UI test more indeph

• Started leaning Git more with commands

• SQL - can manipulate simple databases and more one from scratch

& huge thanks to my sister @niyacodes for being on this journey with me 💓

++++ I went to a 5 hour exam for all these subjects (+- more) and got the highest grade possible 🥹 (i failed my first programming exam in 1st sem!!!!) ((pic is my favorite after study-snack))

Quote of the Week

Panstromek: I remember reading somewhere (probably here) that borrow checking has O(n^3) asymptotic complexity, relative to the size of the function.

Nadrieril: Compared to match exhaustiveness which is NP-hard and trait solving which is undecidable, a polynomial complexity feels refreshingly sane.

– Panstromek and Nadrieril on zulip

Hide Job Listings From Companies You Are Not Interested On LinkedIn (extension for Firefox & Chrome)

Have you noticed that some companies have a bit too many job listings on LinkedIn? Have you ever wanted to hide some of those companies from your suggestions? With the help of this Chrome extension "Hide Items By Link" you can do just that, as the name suggests you can hide elements by a given link on them, but it also supports hidding by any text you have selected! Select the name of the company then right-click it and click "Hide items that contain this text" and that's it; here is a gif showing as much:

This extension is also available for Firefox, which is important to notice has a more granular security model because it requires you to grant access to the extension for each domain (Firefox will show such prompt at the top right corner after you try to use it for the first time).

What else can it do?

Another useful thing you can do with this is to hide Google results from sources you don't want to see, as seen in the following gif:

It can also help you hide channels you dislike from the search results at YouTube, just right-click over the channel name and select "Hide items with this link".

this method is a bit more reliable than text selection but on many websites items do not share a common link (like the channel link in this case) so its not always possible to use this.

While you are here...

My name is Ivan and I'm the creator of this extension, I live in Colombia and at the moment I'm looking for a remote job as Full-Stack Engineer so if you or you company are interested in hiring just let me know! My target salary is 48k (yearly) I have more than 10 years of experience with JavaScript, as well as a few years with TypeScript, React, Python, PHP, Git, Node and many other technologies, as well as software practices such as SOLID architecture, unit testing, regression testing, and e2e testing. You may write me to ivanca at gmáil.
