array.sort((x, y) => +new Date(x.createdAt) - +new Date(y.createdAt));sort array by date typescript
array.sort((x, y) => +new Date(x.createdAt) - +new Date(y.createdAt));How to sort an object array by date property?
// 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
array.sort(function(o1,o2){
if (sort_o1_before_o2) return -1;
else if(sort_o1_after_o2) return 1;
else return 0;
});
// Or more tersely:
array.sOr more tersely:ort(function(o1,o2){
return sort_o1_before_o2 ? -1 : sort_o1_after_o2 ? 1 : 0;
});
// -------------------
// Generic, Powerful Answer
