ES6对象字面量三大新特性详解：属性简写、方法简写与计算属性名

function getInfo(name, age, weight) {
 return {
  // 如果属性名和属性值同名可以利用、es6的属性简写
  name, // 等同于 make: make
  age, // 等同于 model: model
  weight, // 等同于 value: value

  // ES6的属性名是可计算的
  ['over' + weight]: true,

  // 对象方法名简写可以省略 function 关键字
  descripte() {
   console.log(name, age, weight);
  }
 };
}

let person = getInfo('Kia', 27, 400);
console.log(person);// {name: "Kia", age: 27, weight: 400, over400: true, descripte: ƒ}

//ES5
function createPeople(name, age) {
 return {
  name: name,
  age: age
 };
}

function createPeople(name, age) {
 return {
  name,
  age
 };
}

var people = {
 name: 'xixi',
 sayName: function () {
  console.log(this.name);
 }
};

let people = {
 name: 'xixi',
 sayName() {
  console.log(this.name);
 }
};
people.sayName();// xixi

let lastName = 'last name';
let person = {
 [lastName]: 'yuan'
};
console.log(person[lastName]);// yuan
