Polymorphism in Javascript

Polymorphism is a fundamental concept in object-oriented programming (OOP) languages, allowing the same function to be called with different signatures and enabling flexibility and adaptability in code design. In JavaScript, polymorphism is achieved through prototype inheritance and method overloading. It enhances code flexibility, extensibility, and reuse by allowing objects to exhibit multiple forms and behaviors based on their context. Different types of polymorphism in JavaScript include ad-hoc polymorphism, parametric polymorphism, subtype polymorphism, dynamic polymorphism, and compile-time polymorphism. Polymorphism is also leveraged in functional programming and can be applied in various design patterns, such as the strategy pattern, template method pattern, and visitor pattern.
