Fix the method copied onto the instance — find the bug

class Person {
  constructor(name) {
    this.name = name;
    this.greet = function () {
      return "hi";
    };
  }
}
const keys = Object.keys(new Person("Ada"));
document.querySelector('#out').textContent = keys.length === 1 ? "just name" : "also carries " + (keys.length - 1) + " method";
