Sort array by datetime

sortByDateTiem

// Let's say you have collection of things, like:
var collection = [
	{name: '#1 thing', time: '2012-03-16T07:22Z'},
	{name: '#2 thing', time: '2012-03-15T12:00Z'},
	{name: '#3 thing', time: '2012-03-17T20:25Z'},
	{name: '#4 thing', time: '2012-03-13T13:45Z'}
];

// the sorting function
function sortByDateTime(a, b) {
	// check this docs page from mozilla
	// https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort
	// we use date objects to get milliseconds values
	return new Date(a.time).valueOf() - new Date(b.time).valueOf();
}

// Apply the sort function
collection.sort(sortByDateTime);

// See te results
console.log(collection);
