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

Here's a slightly modified version of @David Brainer-Bankers answer that sorts alphabetically by string, or numerically by number, and ensures that words beginning with Capital letters don't sort above words starting with a lower case letter (e.g "apple,Early" would be displayed in that order).

function sortByKey(array, key) {
    return array.sort(function(a, b) {
        var x = a[key];
        var y = b[key];

        if (typeof x == "string")
        {
            x = (""+x).toLowerCase(); 
        }
        if (typeof y == "string")
        {
            y = (""+y).toLowerCase();
        }

        return ((x < y) ? -1 : ((x > y) ? 1 : 0));
    });
}
