<h1>JavaScript Class Static 方法</h1>
​
<p>static 方法是使用 "static" 关键字创建的，您只能在类本身上调用该方法。</p>
​
<p id="demo"></p>
​
<script>
class Car {
  constructor(name) {
    this.name = name;
  }
  static hello() {
    return "Hello!!";
  }
}
​
let 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.
