Well, I like to not just memorize blocks of code, but to understand them, so that I can create them myself. Why does this work? I don't understand. If someone can explain it to me, I'd be most grateful. To me it looks like: If the array index (position in the array) is greater than 0, 0 = the array index, and how that would magically tell me the highest number in the array I haven't a single clue. I've tried searching for an answer on this but without luck. Here's an example of the code, thanks in advance:

var array = [3, 4, 5, 21.15, 21, 9];

var largest = 0;



for (i = 0; i < array.length; i++) {

    if (array[i] > largest) {

        largest = array[i];

    }

}

console.log(largest);​
