javascript closure application code example

Example 1: closure in js

A closure gives you access to an outer function’s scope from an inner function
//example
function init() {
  var name = 'Mozilla'; // name is a local variable created by init
  function displayName() { // displayName() is the inner function, a closure
    alert(name); // use variable declared in the parent function
  }
  displayName();
}
init();
