Scenario

Have have the following Typescript class instances:

class DateClass {
    constructor(public name: string, public receiptDate: Date) {}
}
const d1 = new DateClass('d1', new Date(3));
const d2 = new DateClass('d2', new Date(2));
const arr: DateClass[] = [d1, d2];

And we wish to sort them in the following order:

[d2, d1]

Approach

const sorted = arr.sort((a, b) => {
return a.receiptDate.getTime() - b.receiptDate.getTime();
});
console.log(sorted);
