Sort array of JavaScript objects by property value

arrays, javascript, lodash, sorting

Solution

I just went through lodash doc, and perhaps you could try `sortBy`

Try it: http://jsfiddle.net/3Wza8/

var myObjects = [
    { id: '1', username: 'bill.jones', active: true, createdon: new Date('03/29/2014') },
    { id: '2', username: 'woohoo', active: true, createdon: new Date('03/28/2014') },
    { id: '3', username: 'someuser', active: true, createdon: new Date('03/30/2014') }
];

myObjects = _.sortBy(myObjects, 'createdon');

_.forEach(myObjects, function (result) {
    console.log(result);
});

EDIT: as Cookie Monster pointed out, it's important that your `createdon` field is a Date, and not a string.

Problem

I have an array of JavaScript objects. My array is defined like this: ``` var myObjects = [ { id: '1', username: 'bill.jones', active: true, createdon: '03/29/2014' }, { id: '2', username: 'woohoo', active: true, createdon: '03/28/2014' }, { id: '3', username: 'someuser', active: true, createdon: '03/30/2014' } ]; ``` This array is actually dynamically populated. Still, I need to sort the results by the createdon value in ascending order. To do that, I'm trying to use lodash. The createdon value represents a date. Currently, I'm trying the following: ``` // ORDER BY createdOn myObjects.sort(function (a, b) { var date1 = new Date(a['createdon']); var date2 = new Date(b['createdon']); return date1 < date2; }); _.forEach(myObjects, function(result) { console.log(result); }); ``` Unfortunately, myObjects is still not sorted after I run this function. What am I doing wrong? Thank you!
