OOP vs POP: Difference Between OOP and POP

When it comes to programming, there are two main paradigms that are often used: object-oriented programming (OOP) and prototype-based programming (POP). Both approaches have their own strengths and weaknesses, so it's important to understand the key differences between them.

Classes vs. Objects

In OOP, everything is based on classes. A class is like a blueprint for an object, specifying what attributes and methods it has. Once you have created a class, you can then create objects that belong to that class.

In POP, there are no classes. Instead, everything is based on objects. An object can inherit from other objects, but there is no concept of a class that acts as a blueprint.

Encapsulation

Encapsulation is a key concept in OOP. It refers to the idea of hiding the implementation details of an object from the outside world. By encapsulating an object, you can control how it is used and accessed by other parts of your code. This makes your code more robust and easier to maintain.

Inheritance

Inheritance is another key concept in OOP. It refers to the ability of one class to inherit the attributes and methods of another class. This allows you to create hierarchies of classes, where each subclass inherits from its parent class.
