Starting a New Project

Login to your GitHub account and create a new repository.
Copy the generated URL which looks something like this: https://github.com/iamoperand/test123.git
Now, create a new folder in your system.
Open terminal in that location and then follow the following commands:

git init //to initialise GIT in the target location
git add --all //to add all the files (staging is what it means, done just before committing)

1. Clearing the confusion between prototype, proto and [[Prototype]]

prototype

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

2. How "new" keyword works in JS

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

3. How "super" keyword works in JS

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

This issue can be summarised as follows:

The JS engine only attaches an object instance to the context variable (this) once you get to the highest prototype in the chain - which is Object

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; }

	//Fat-Arrow syntax
	var blog = {
	name: 'The School Of JS',
	topics: ['DOM', 'JS'],
	about: function () {
	return this.topics.map(topic => topic + ' is a topic of ' + this.name + ' blog!');
	}
	};

	blog.about();

	{
	"workbench.colorTheme": "Cobalt2",
	"files.autoSave": "onFocusChange",
	"editor.fontFamily": "Operator Mono, Menlo, Monaco, 'Courier New', monospace",
	"editor.fontSize": 17,
	"editor.lineHeight": 25,
	"editor.letterSpacing": 0.5,
	"files.trimTrailingWhitespace": true,
	"editor.fontWeight": "400",
	"prettier.eslintIntegration": true,

	// The Problem
	function fn(val) {
	setTimeout(function() {
	console.log(val)
	}, val)
	}

	function executeAll() {
	fn(20)
	fn(20)

	EPV(t) = E[points \| d(t)] = E[points \| macro in (t, t+ε], d(t)] × P(macro in t(t+ε] \| d(t))
	+ e[points \| micro in (t, t+ε], d(t)] × P(micro in t(t+ε] \| d(t))
