--description--

ES6 添加了一些很棒的功能,以便于更方便地定义对象。

请看以下代码:

const getMousePosition = (x, y) => ({
  x: x,
  y: y
});

getMousePosition是一个返回了拥有2个属性的对象的简单函数。 ES6 提供了一个语法糖,消除了类似x: x这种冗余的写法.你可以仅仅只写一次x,解释器会自动将其转换成x: x。 下面是使用这种语法重写的同样的函数:

const getMousePosition = (x, y) => ({ x, y });

--instructions--

请使用简单属性对象的语法来创建并返回一个Person对象。

--hints--

输出是{name: "Zodiac Hasbro", age: 56, gender: "male"}

assert.deepEqual(
  { name: 'Zodiac Hasbro', age: 56, gender: 'male' },
  createPerson('Zodiac Hasbro', 56, 'male')
);

不要使用key:value

(getUserInput) => assert(!getUserInput('index').match(/:/g));

--seed--

--seed-contents--

const createPerson = (name, age, gender) => {
  // Only change code below this line
  return {
    name: name,
    age: age,
    gender: gender
  };
  // Only change code above this line
};

--solutions--

const createPerson = (name, age, gender) => {
  return {
    name,
    age,
    gender
  };
};
