Lifecycle of a web-app

Browser-side and Server-side

Client makes a request from the browser which then goes to the server to fetch some resources.

I have found a collection of blogs that will help you understand it. The links are as follows:

1. Why is it important? (the use case)
2. Public Class Fields in React

4. How "this" keyword works with functions JS

To access any variable or any method that is a part of a JavaScript object, we use "this" keyword.

For example,

function Dog(name) {
 if (name) { this.name = name; }

3. How "super" keyword works in JS

The main issue that we will come across in React is the usage of "this" in constructor.

2. How "new" keyword works in JS

  function Dog(name) {
    if (name) { this.name = name; }
    this.speak = function() {
        return this.name + " says woof";
    }
  }
