587d7b8a367417b2b2512b4f Write Concise Object Literal Declarations Using Simple Fields 1 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 =xy=>{
xx
yy
};
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 =xy=>{xy};

Instructions

使用带有对象文字的简单字段来创建和返回Person对象。

Tests

tests:
  - text: '输出是<code>{name: &quot;Zodiac Hasbro&quot;, age: 56, gender: &quot;male&quot;}</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.");'

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
