js设置键名和键值
let obj1 = {'jifeng': 60, 'lilu': 59, 'hongyan': 51, 'donghan': 4,

// let res = Object.keys(obj1).map(value => ({obj2[value]:obj1[value]}))
let res = Object.keys(obj1).map(value => {
let newObj = {}
newObj[obj2[value]] = obj1[value]
return newObj
})
console.log(res)
是20行而不是19行,因为js中键名不能使表达式,只会定义不会执行,
newObj的键名是 obj2[value]的返回值。
