OOP (Object-Oriented Programming) — OOP Summary

OOP is a powerful programming approach that organizes code into reusable, modular, and logical pieces. The four main principles are Encapsulation, Abstraction, Inheritance, and Polymorphism. By using these principles, developers can create software that is easier to understand, maintain, and extend. OOP is used in many programming languages such as Java, Python, C++, and C#. Understanding classes, objects, and their relationships is key to mastering OOP. With practice, OOP helps you write cleaner, more efficient, and professional code for real-world applications.

// Example showing multiple OOP concepts
class Vehicle {
  move() { console.log('Vehicle is moving'); }
}
class Car extends Vehicle {
  move() { console.log('Car is driving'); }
}
let v = new Vehicle();
let c = new Car();
v.move();
c.move();
