準備測試數據

var data=?[{name:"Jackie",id: "122"}, {name:"Tony2",id: "121"}, {name:"Tony",id: "121"}];

find?查找?返回第一個符合條件的結果

data.find(user=>user.id==='121')--結果
{name: "Tony2", id: "121"}

filter?過濾?返回所有符合條件的結果

data.filter(user=>user.id==='121')--結果
(2)?[{…}, {…}]
0: {name: "Tony2", id: "121"}
1: {name: "Tony", id: "121"}
length: 2
__proto__: Array(0)

sort?按指定條件排序

--根據id 由小到大排序data.sort((a, b) => (a.id > b.id) ? 1 : ((b.id > a.id) ? -1 : 0))--結果
(3) [{…}, {…}, {…}]
0: {name: "Tony2", id: "121"}
1: {name: "Tony", id: "121"}
2: {name: "Jackie", id: "122"}
length: 3
__proto__: Array(0)
