Unlike any other programming languages in JavaScript, polymorphism provides an ability to call the same method on different JavaScript objects. As JavaScript is not a type-safe language, we can pass any type of data members with the methods.

Why Polymorphism?

Imagine you have a universal remote control. You press the "power" button, and it turns on your TV. You press the same "power" button, and it adjusts the volume on your sound system.

Similarly, in JavaScript, polymorphism allows you to use the same method or function name in different objects, and each object can perform its unique action.

Flexibility and Reusability:

With your universal remote, you don't need a different remote for each device. You can use one remote for various electronics.

In JavaScript, polymorphism provides flexibility. You can write functions or methods that can work with different types of objects, making your code more reusable.

Let's see an example
