var	let
’var’ keyword was introduced in JavaScript code from the beginning Stage itself.	‘let’ keyword is introduced in 2015 only.
’Var’ keyword has function scope. The variable defined with var is available anywhere within the function	A variable declared with ‘let’ keyword has scope only within that block. So, let has a Block Scope.
The variable declared with ‘var’ be hoisted	The variable declared with ‘let’ be hoisted
