--- 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 <section id="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: <blockquote> const getMousePosition =(x,y)=>({ <br> x:x, <br> y:y <br> }); </blockquote> <code>getMousePosition</code>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<code>x: x</code>的冗余。您可以简单地编写一次<code>x</code> ,它将被转换为<code>x: x</code> (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: <blockquote> const getMousePosition =(x,y)=>({x,y}); </blockquote></section> ## Instructions <section id="instructions">使用带有对象文字的简单字段来创建和返回<code>Person</code>对象。 </section> ## Tests <section id='tests'> ```yml tests: - text: '输出是<code>{name: "Zodiac Hasbro", age: 56, gender: "male"}</code> 。' 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 <code>{name: "Zodiac Hasbro", age: 56, gender: "male"}</code>.");' - text: '不<code>:</code>被使用了。' testString: 'getUserInput => assert(!getUserInput("index").match(/:/g), "No <code>:</code> were used.");' ``` </section> ## Challenge Seed <section id='challengeSeed'> <div id='js-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 ``` </div> </section> ## Solution <section id='solution'> ```js // solution required ``` </section>
