The Constructor

Initialize new instances

The constructor method initializes new instances. It receives arguments passed to new and sets up instance properties.

class Rectangle {
  constructor(width, height) {
    this.width = width;
    this.height = height;
  }
}

const rect = new Rectangle(10, 5);
console.log(rect.width); // 10
