--- id: 587d7b8a367417b2b2512b4f title: Write Concise Object Literal Declarations Using Simple Fields challengeType: 1 videoUrl: '' localeTitle: 使用简单字段编写简明对象文字声明 --- ## Description
ES6为轻松定义对象文字添加了一些很好的支持。请考虑以下代码:
const getMousePosition =(x,y)=>({
x:x,
y:y
});
getMousePosition是一个简单的函数,它返回一个包含两个字段的对象。 ES6提供了语法糖,以消除必须写入x: x的冗余。您可以简单地编写一次x ,它将被转换为x: x (或类似的东西)。这是从上面重写的相同函数使用这个新语法:
const getMousePosition =(x,y)=>({x,y});
## Instructions
使用带有对象文字的简单字段来创建和返回Person对象。
## Tests
```yml tests: - text: '输出是{name: "Zodiac Hasbro", age: 56, gender: "male"} 。' testString: 'assert(() => {const res={name:"Zodiac Hasbro",age:56,gender:"male"}; const person=createPerson("Zodiac Hasbro", 56, "male"); return Object.keys(person).every(k => person[k] === res[k]);}, "the output is {name: "Zodiac Hasbro", age: 56, gender: "male"}.");' - text: '不:被使用了。' testString: 'getUserInput => assert(!getUserInput("index").match(/:/g), "No : were used.");' ```
## Challenge Seed
```js const createPerson = (name, age, gender) => { "use strict"; // change code below this line return { name: name, age: age, gender: gender }; // change code above this line }; console.log(createPerson("Zodiac Hasbro", 56, "male")); // returns a proper object ```
## Solution
