Closures

A CLOSURES is the combination of a function bundled together with references to its surrounding state (the lexical scope - Scope session).
A CLOSURES gives you access to an outer function’s scope from an inner function.
Closures are created every time a function is created, at function creation time.
To create a closures just by simply create a function inside a function.
CLOSURES is common way to create data privacy. It's likely property accessor.

function showName (firstName, lastName) {

var nameIntro = "Your Name is";

function makeFullName () {

return nameIntro + firstName + " " + lastName;

return makeFullName ();

showName ("Jack", "Diff");
