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; }; Stayed Informed - How do you define a class and its constructor?
