A function

A function is a block of statements that can be used in a file.
I will create a function to change the color of my notes.

function colorMyNotes() {
    var i;
    var postItNoteColors = [
        '#FCF0AD', '#E9E74A', '#EE5E9F', '#FFDD2A', '#F59DB9', '#F9A55B', '#D0E17D', '#36A9CE', '#EF5AA1', '#AE86BC', '#FFDF25', '#56C4E8', '#D0E068', '#CD9EC0', '#ED839D', '#FFE476', '#CDDD73', '#F35F6D', '#FAA457', '#35BEB7', '#D189B9', '#99C7BC', '#89B18C', '#738FA7', '#8A8FA3', '#82ACB8', '#F9D6AC', '#E9B561', '#E89132', '#DA7527', '#DEAC2F', '#BAB7A9', '#BFB4AF', '#CDC4C1', '#CFB69E', '#D0AD87'];
    var i = 1;
    $('.col-md-4').each(function() {
        $(this).css('background-color', postItNoteColors[i]);
        i = (i + 1) % postItNoteColors.length;
    });
}
colorMyNotes();

The function works, however the color is always the same and it would be nice if it was random. Next, create an array that will randomize the color.
