// Sort by date
array.sort((a,b) => new Date(b.date) - new Date(a.date));
typescript sort array of objects by date descending
arr = arr.sort(function (a, b) {
var dateA = new Date(a.date_prop).getTime();
var dateB = new Date(b.date_prop).getTime();
return dateA < dateB ? 1 : -1; // ? -1 : 1 for ascending/increasing order
});
array.sort(function(a,b){
// Turn your strings into dates, and then subtract them
// to get a value that is either negative, positive, or zero.
return new Date(b.date) - new Date(a.date);
});
// Simplest Answer
array.sort(function(a,b){
// Turn your strings into dates, and then subtract them
// to get a value that is either negative, positive, or zero.
return new Date(b.date) - new Date(a.date);

// More Generic Answer

// Or more tersely:
array.sOr more tersely:ort(function(o1,o2){
return sort_o1_before_o2 ? -1 : sort_o1_after_o2 ? 1 : 0;
