Hello stackoverflow!

I have a certain loop occurring several times in various functions in my code. To illustrate with an example, it's pretty much along the lines of the following:

for (var i=0;i<= 5; i++) {
    function1(function2(arr[i],i),$('div'+i));
    $('span'+i).value = function3(arr[i]);
}

Where i is the loop counter of course. For the sake of reducing my code size and avoid repeating the loop declaration, I thought I should replace it with the following:

function loop(s) {
 for (var i=0;i<= 5; i++) { eval(s); }
}

[...]

loop("function1(function2(arr[i],i),$('div'+i));$('span'+i).value = function3(arr[i]);");

Or should I? I've heard a lot about eval() slowing code execution and I'd like it to work as fast as a proper loop even in the Nintendo DSi browser, but I'd also like to cut down on code. What would you suggest?

Thank you in advance!
