/*scope variable
//var doesn't have block scope
block scope {var x=2;}
{
    let x=2;
    var j=2;
}
console.log(x);

not able to access x as it is inside block scope


function scope
function myFunction(){
var firstName = "krishna"; //function scope
}

example:
function pname()
{
var name = "shr";
}

console.log(name);
pname;

global scope

can access from anywhere

let x=2; //global scope
const x=2; //global scope
var x=2; //global scope
