Interface with JavaScript

Interface: An interface is an blue print of a class, it specify what methods an Object should have, that way it add some kind of predictability on what you can expect from that Class. For example, a Class that implement “Comparable” interface can be assumed to be comparable with other object that implement “Comparable” interface. It allows you to group objects on the features they provide. It make sure all Classes of required feature follows same methods, hence communication between them easier. In a way it also increases code re-usage.

JavaScript doesn’t have native support for interfaces along with normal object oriented features of other languages like C++ and Java. There is no interface keyword in JavaScript, apart from this emulating interfaces feature will add some performance over head and will reduce the flexibility of JavaScript to some extent. Transition for other language codes to JavaScript may be a tedious task, if you developing completely new Class, you can make sure all implementations are at their best ability. Biggest of the problems in using interfaces with JavaScript is there is no way you can force other programmers to use the interfaces you created.
