Object-Oriented Programming (OOP) is a powerful programming approach that organizes code through real-life-like objects. In this, we group data (properties) and actions (methods) into a single unit called an object — this process is known as encapsulation. In OOP, classes are created that work as templates, and multiple objects can be created from them. This makes the code reusable, manageable, and extendable. Through inheritance, one class can use the features of another class, which reduces duplication. Polymorphism allows us to use the same method in different ways. OOP is widely used in large-scale software, games, websites, and applications because it brings structure and flexibility to the code. Languages like JavaScript, Python, Java, and C++ fully support OOP...
