Sort array of objects by single key with date value

Question

I have an array of objects with several key value pairs, and I need to sort them based on \'updated_at\':

[
    {
        \"updated_at\" : \"2012-01-01T06:25         


        

Answer 1

Use underscore js or lodash,

var arrObj = [
    {
        "updated_at" : "2012-01-01T06:25:24Z",
        "foo" : "bar"
    },
    {
        "updated_at" : "2012-01-09T11:25:13Z",
        "foo" : "bar"
    },
    {
        "updated_at" : "2012-01-05T04:13:24Z",
        "foo" : "bar"
    }
];

arrObj = _.sortBy(arrObj,"updated_at");

_.sortBy() returns a new array
