In javascript, the variable scope and its hoisting are quite different.Let’s take an example – var car = “Mercedes” // variable is defined in the global scope
function car_name () { // function
car = “BMW”; // this is a local scope but the variable car is global variable
var car = “Benteley” // this is a variable that is defined in local scope and is local variable
