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 codeCopyright © 2021 Codeinu
