数组对象排序

const ArrayList = [{ "val": 9 },
{ "val": 8 },
{ "val": 7 },
{ "val": 6 },
{ "val": 5 },
{ "val": 4 },
{ "val": 3 },
{ "val": 2 },
{ "val": 1 }]
ArrayList.sort((a, b) => {
  return a.val - b.val
})//正序是a-b   反序b-a
console.log('[ ArrayList ]', ArrayList)//[ ArrayList ] [{ val: 1 }, { val: 2 },{ val: 3 }, { val: 4 },{ val: 5 }, { val: 6 },{ val: 7 }, { val: 8 },{ val: 9 }]
