JavaScript Class Inheritance

Classical inheritance in JavaScript, introduced in ES6, utilizes the class and extends keywords to enable inheritance and method overloading, making it similar to languages like Java or C++. The super keyword allows access to parent class properties and methods, while static members demonstrate inheritance independently of class instances. This approach provides a structured way to create reusable and hierarchical object relationships.

Functional inheritance, on the other hand, uses function constructors to establish relationships between objects, allowing for constructor overriding and method customization. JavaScript also supports extending built-in data types like Array and Error to create custom classes with added functionality. These inheritance models, both classical and functional, offer flexibility for designing robust and modular applications.
