Learning JavaScript

This repository contains a set of Code Kata I've used to practice and learn JavaScript.

How to run the examples

1. Fetch all dependencies

npm install

2. Run all the tests

npm test

3. Run all the tests with coverage reports

npm run coverage

Resources I found about JavaScript

In JavaScript there is NO concept of Class.

Everything is an Object.

Inheritance between objects is achieved with a mechanism known as Prototypal Inheritance.

We can create Objects and then link them together OLOO (Objects-Linked-to-Other-Objects).

Testing and JavaScript

• JavaScript Unit Testing for Beginners
• Video about Setting up Unit Testing with Mocha and Chai
• Video about Unit Testing With Mocha and Chai
• Ended up with Chai as assertions library, and Mocha as test runner
  • Discovered that Chai allows three different assertion styles (Should, Expect and Assert). It's just a matter of style.
  • But there is also another Testing Framework to experiment with, Jest.
