JS Class Static Methods

A static method is created with the "static" keyword, and you can only call the method on the class itself.

class Car {
  constructor(name) {
    this.name = name;
  }
  static hello() {
    return "Hello!!";
  }
}

const myCar = new Car("Ford");

//You can call 'hello()' on the Car Class:
document.getElementById("demo").innerHTML = Car.hello();

// But NOT on  a Car Object:
// document.getElementById("demo").innerHTML = myCar.hello();
// this will raise an error.
