I'd rather rewrite code any-day then fix someone else's... i'd be
willing to wager that i'm saving time too. I comment my code a bit,
but i only take the time to do any docs if a client feels very
strongly about it.

"upgrade from
AS1 to AS2" or "Flash to Flex".
If Flash stops changing, and the code that keeps getting thrown at me
actually works for a change and is malleable, then I could see the
point of
commenting. Currently, nope.

This happens all too often. As common as this is, it is something you
*must* do. Especially if you are the person that has to go back and
change stuff at a later date. I dont know how many times I have gone
back and looked at my code and I was like, "what the (explicitive
deleted) was I doing". Now I write code for readability.
// bad (IMHO)
if (getIsTrue(myTest)) {
return (10/2 + 5)/mc._x;
}
// good
var isSomethingTrue = getIsTrue(myTest)
if (isSomethingTrue) {
var retVal = (10/2 + 5)/mc._x;
return retVal;
}
Trust me dude, I am having to rewrite an asp app in flash remoting
asp.net and none of the code is commented. So I have spent 3/4ths
of my
time trying to interprit another persons code and the other half
writing
a flash remoting version of it. Readability is more important than
speed
(IMHO). Either way comment. :)

...not to mention most service work is always a custom job/rewrite
anyway.

I think these are all great, but if I can be the voice of caution for
a moment...
remember that when you write code, it is for 2 interpreters:
1) the Actionscript VM
2) the person who has to go back and change stuff at a later date,
which may or may not be you...
Its often very easy to forget number 2 - so, while writing doing
things like avoiding function calls may be faster for 1) it can
end up
making things a lot slower for 2)
Also, when you go through your code & optimise it, make sure you are
efficient with your efforts - you will probably find you can nail
down
key performance spikes to just a few functions / algorithms... be
careful not to optimise to death, and try and measure your gains at
each step
I'm not saying code shouldnt be optimised at the expense of (human)
readability, just that sometimes it gets a little overdone...

the fastest loop through an array is:

yes, it's faster then for..in.
Not always. Sometimes, this loop is faster than a while (i--)
for (var i = items.length; --i - (-1); ) {
...
}
It's ugly, yes, but it is faster than while (i--) depending on
how many
items you're iterating through. Run some tests if you don't
believe me.
