Object oriented programming
a.k.a. OOP
An imperative programming paradigm that uses classes for abstraction, encapsulation, and polymorphism.
Example
class Rectangle {
constructor(width, height) {
this.width = width;
this.height = height;
}
getArea() {
return this.width * this.height;
}
}
class Square extends Rectangle {
constructor(size) {
super(size, size);
}
}
const rect = new Rectangle(5, 2);
rect.getArea();

const square = new Square(6);
square.getArea();
