    I’m in the middle of learning JS and jQuery. I try and create a random tool at least once a week to test how my learning is going, and this is my latest experiment:

    Now, originally, I was using nested for loops (, but I have since discovered that this is a bad idea for performance reasons. I have defined functions to try and get around this, but is defining a function inside another function just as bad?

    What is the best way to do what I am trying to do? Have you got any other improvements for me? Thanks in advance guys.

    Slightly related aside; should I define a function like this:

    function foo() {

    Or like this:

    var foo = function() {

    @joshuanhibbert – nice application, josh. I am also learning jquery at the moment and was wondering how you go about setting yourself projects? I am working purely off exercise files at the moment and thought it would be good to move away from that and do my own stuff. The problem is I find it hard choosing what to do. Any suggestions?


    Great idea. Thanks @karlpcrowley


    @Hompimpa LOL! You and your forking antics ;)

    I struggle with finding things to create and practise with too, but any time something pops into my head (usually from a discussion with someone) I attempt to create a tool. I much prefer creating my own stuff over following tutorials, and I find that having to figure out issues on my own is the best way to learn. The other thing I do is try to recreate popular things on my own. Things like this, this, this, this, this, this, this, and this.

    Not all of those are working 100%, but feel free to play around with them!

    Thanks for those links mate, I’ll have a look at them now! Great looking fork too :D


    @karlpcrowley That article explained defining functions perfectly. Thanks Karl!

    Also, that inception gist is awesome!


    @joshuanhibbert – thanks very much for that. I think that is really good advice. Sometimes I am keen to move on quickly after finishing tutorials and come to doubt myself later as to how much I have absorbed. I think what you are doing sounds like the best method.


    @tobeeornot No worries. Good luck with your learning!
