How to sort an array of objects by date?

As has been pointed out in the comments, the definition of recent isn't correct javascript.

But assuming the dates are strings:

var recent = [    {id: 123,age :12,start: "10/17/13 13:07"},     {id: 13,age :62,start: "07/30/13 16:30"}];

then sort like this:

recent.sort(function(a,b) {     return new Date(a.start).getTime() - new Date(b.start).getTime() });

recent.sort(function(a,b) { return new Date(a.start).getTime() - new Date(b.start).getTime() } );

This function allows you to create a comparator that will walk a path to the key you would like to compare on:

function createDateComparator ( path = [] , comparator = (a, b) => a.getTime() - b.getTime()) {  return (a, b) => {    let _a = a    let _b = b    for(let key of path) {      _a = _a[key]      _b = _b[key]    }    return comparator(_a, _b)  }}const input = (  [ { foo: new Date(2017, 0, 1) }  , { foo: new Date(2018, 0, 1) }  , { foo: new Date(2016, 0, 1) }  ])const result = input.sort(createDateComparator([ 'foo' ]))console.info(result)
