5 Key Object-Oriented Programming Concepts in JavaScript for Modern Development

1. Inheritance:

Inheritance lets one class use the properties and methods of another class. This means you can create a new class based on an existing one, reusing code and making it easier to manage.

2. Polymorphism:

Polymorphism allows objects to be treated as instances of their parent class, even if they have different implementations. It enables flexibility in code, letting you work with different objects in a consistent way.

3. Abstraction:

Abstraction hides the complex details of how things work and only shows the essential features. In JavaScript, you can use classes and objects to create a simplified interface for interacting with your code.

4. Classes and Objects:

Classes are blueprints for creating objects. Objects are specific instances of classes that contain data and methods. Using classes and objects helps you build well-structured and scalable applications in JavaScript.

5. Encapsulation:

Encapsulation groups related data and functions into a single object. This keeps the internal workings of the object private and only exposes what is necessary. It makes your code more organized and easier to maintain.
