JavaScript Classes

Introduction

Syntax

1/* class syntax */
2class ClassName {
3  constructor() { ... }
4}

Example

1/* this creates a class */
2class Car {
3  constructor(brand) {
4    this.carname = brand;
5  }
6}
7let myCar = new Car("Ford");

Key Points

• The `class` keyword defines the template.
• The `constructor()` method runs automatically when creating a new object.
• The `new` keyword creates an object from the class.
• Classes act as a cleaner syntax for older prototype patterns.
