依据日期先后顺序排序

SortByDate.js

let array = [{id: 2, date: "2019/1/28"}, {id: 3, date: "2019/1/1"}, {id: 1, date: "2019/7/19"}];

array.sort(function(a,b){
  return new Date(b.date) - new Date(a.date);
});

// Output
// [{id: 1, date: "2019/7/19"}, {id: 2, date: "2019/1/28"}, {id: 3, date: "2019/1/1"}];
