In this post, I am share the “Why self is needed instead of this in JavaScript?” and ALSO what is the advantage of using “var self = this;”

var self = this;

In the JavaScript, “self” is a pattern to maintaining a reference to the original “this” keyword and also we can say that this is a technique to HANDLE the events.

RIGHT now, “self” should not be used because modern browsers provide a “self” as global VARIABLE (window.self).

Example [“self” keyword is needed instead of “this”],

var employee = function (name) {

var self = this;
self.username = name;
};
