Access overridden global variable inside a function

Question

I want to access global variable \'x\' when it is over-ridden by same named variable inside a function.

function outer() {
   var x = 10;
   function overRid         


        

Answer 1

The global scope of your web page is window. Every variable defined in the global scope can thus be accessed through the window object.

var x = 10;
function overRideX() {
    var x = "Updated";
    console.log(x + ' ' + window.x);
}();

Answer 2

You can use window.x to reference the globally scoped variable.

var x = 10;
function overRideX() {
  var x = "Updated";
  console.log(x);
  console.log(window.x);
};

overRideX();

This code logs "Updated" then 10.
