如何在js中创建对象

const o = {
  name: "zehan",
  greeting() {
    return `Hi, 我是${this.name}`;
  }
};

o.greeting(); // "Hi, zehan"

function Person(name) {
   this.name = name;
}

Person.prototype.greeting = function () {
   return `Hi, 我是${this.name}`;
}

const mark = new Person("zehan");

mark.greeting(); // "Hi, 我是zehan"

const n = {
   greeting() {
      return `Hi, 我是${this.name}`;
   }
};

const o = Object.create(n); 
o.name = "zehan";
