Defining an Interface

In JavaScript, an interface can be thought of as a set of method signatures that a class must implement. You can define an interface as an empty object containing method names and their associated function signatures.

Example:

const MyInterface = {
method1: function () { },
method2: function (param1, param2) { },
};

Implementing Interfaces in JavaScript

In JavaScript, there is no built-in concept of interfaces like you might find in languages like Java or C#. However, you can achieve similar functionality by defining and implementing your own interfaces using objects and classes. In this explanation, this article will guide you through the process of implementing interfaces in JavaScript.
