js 实现json数组时间排序

NewsList=[

{"time":1531995239981,"level":"小乔"},

{"time":1531994874457,"level":"露娜"}

{"time":1531995513155,"level":"李白"},

{"time":1531995337797,"level":"娜可露露"},

{"time":1531995244188,"level":"貂蝉"},

]

//json时间排序
_SortJson(json) {
json.sort(function (a,b) {
// console.log('b,a',b,a,a.time - b.time)
return b.time - a.time;//时间反序
});
console.log(json)
}

//调用

_SortJson(NewsList)
