Explain why "self" is needed instead of "this".

Why "self" is needed instead of "this" in JavaScript?

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;
};
