VAR VARIBALE_NAME = []; code example

Example 1: variables in js

Variables can have anything, you define them as equal to something
    
    eg:   var x = 22
    var statement = 'hello!'
    var isAbool = true 
    
    there are three types of variables:
1. var 
2. let
3. const 

var is a normal variable
let is a variable whose value can be changed eg: let h = 12, h = 10(we changed the value, if you run this, there will be no error)
const is a variable whose value cannot be changed, if you change the value of a const, you will have errors in you code

Example 2: js variables

// let & var are both editable variables:
var cow = 'moo';
let pig = 'oink';
cow = 10;
pig = 10;
// const is a permanent variable; you cannot change it.
const uncuttableGrass = '\/\/';
uncuttableGrass = '___';
// above throws an error
