    Is it possible to get the highest string length within an array? I tried looking for a sort function but this doesn't seem to exist.

    you'd have to walk it
    
var maxLength = function(array) {
    var ml = 0, al = array.length;
    while(al--) {
        ml = array[al].length > ml ? array[al].length : ml;
    }
    return ml;
};

words: [
        "guitar",
        "cello",
        "piano",
        "drums",
        "violin",
        "clarinet",
