Hi Sunny Chu,

You can use dot notation on the object followed by the method name you're calling ... e.g.

class Witch {
  constructor(name) {
    this.name = name;
  }

  laugh() {
    alert("Mwhahahahaha....");
  }

  greet() {
    alert("Hi, I'm " + this.name);
  }

}

let nyx = new Witch("Nyx");

nyx.laugh(); // shows alert with "Mwhahahahaha...."
nyx.greet(); // shows alert with "Hi, I'm Nyx"

I hope that helps (and is what you were asking about).
Happy coding, :dizzy:

Dave
