inefficient to check value of a checkbox?

[Kourosh]

I have a big loop that checks the value of a checkbox several times
(1000+ times)
I'm just wondering, would it be any more efficient to save the value of
the checkbox outside the loop and the read that variable inside the
loop instead?

ie, I have this
for (var i=0;...)
doStuff (form1.checkbox1.checked);


versus
var chk = form1.checkbox1.checked;
for (var i=0;...)
doStuff (chk);

Do the second. It keeps from having to look up that property 1000 or so
times and as such will *always* be faster.
