Part 2 - JavaScript - variables and constants

In this video I've covered variables and constants into Javascript. I've also touched upon different primitive and non-primitive data types available into JS.
Variables - Are Symbols or Pointer to memory or storage address e.g. Address of your Home/Office
Primitive Data Types - are data types provided by a programming language as a basic building block
String, Number, Boolean, Undefined, Null, BigInt and NaN

Non-Primitive Data Types
Object - Covered in later part of the course
Date - Covered in later part of the course
Array - Covered in later part of the course
Constants - behave like variables, except they cannot be reassigned and must to be initialized

Also covered escape characters, and Wrapper classes in Javascript
