ES6之对象的方法

const obj = {
  name:'qqq',
  age:10,
  fun:function(){},
  children:[{id:1}]
}

// 1.获取对象的key
let keyArr = Object.keys(obj)

// 2.获取对象的value
let valueArr = Object.values(obj)

// 3.把对象转化为数组
let arr = Object.entries(obj)

// 4.遍历对象
for(let key in obj){
  console.log(key,'对象的key')
  console.log(obj[key],'对象的value')
}
