JavaScript Classes

JavaScript Classes are templates for creating objects. They encapsulate data with code to work on that data.

Class Syntax

Use the keyword class to create a class. Always add a method named constructor():

javascript

class Car {
  constructor(name, year) {
    this.name = name;
    this.year = year;
  }
  age() {
    let date = new Date();
    return date.getFullYear() - this.year;
  }
}

let myCar = new Car("Ford", 2014);
console.log("My car is " + myCar.age() + " years old.");
