js⾯试题：⽤sort实现数组对象指定对象属性排序
补全代码，实现数组按姓名、年纪、任意字段排序。
var users = [
{ name:'freddy', age:24, score:97 },
{ name:'nick', age:18, score:87 },
{ name:'mike', age:26, score:80 },
{ name:'james', age:34, score:90 },
{ name:'curry', age:30, score:83 }
]
users.sort(byField("age"))
users.sort(byField("score"))
实现：
var users = [
{ name:'freddy', age:24, score:97 },
{ name:'nick', age:18, score:87 },
{ name:'mike', age:26, score:80 },
{ name:'james', age:34, score:90 },
{ name:'curry', age:30, score:83 }
]
function byField(m){
function Fun (a,b){
return a[m]-b[m]
}
return Fun
}
var a = users.sort(byField('age'))
console.log(a)
//var b= users.sort(byField("score"))
//console.log(b)
sort函数 js结果：
sort只接收⼀个函数
