' and " benchmarking in JavaScript

[Charles Stover]

I know in PHP ' is faster than " (because PHP doesn't go back and look for characters such as \t or \n when in single quotes), but is the same true in JavaScript? JS parses \t and \n in both single and double, but are there other factors?
I hear Firefox parses double quotes slightly faster (because, if using single quotes, it internally converts them to double). Does anyone have any benchmarking on this?

EDIT:
Also, x++ versus ++x

[Michael]

x++ and ++x are different, so you can't really compare them! :/

[Charles Stover]

They are, for the majority of the time, interchangeable. The question is, during those times, which should you use? The answer is benchmarking.

[Chris]

Why not benchmark it yourself?

[Charles Stover]

Too lazy to look up benchmarking commands in JavaScript. Plus, don't have that many browsers installed on my computer.

[Wormopolis]

just create a REALLY big loop and timestamp it before and after. change what is in the loop to see if there is a huge difference.

[Charles Stover]

I know how to benchmark. =P
I still don't have many browsers.

[SubDevo]

geez Charles, just install the extra browsers. Benchmark, then uninstall if you don't want them... lol
I keep 5 different browsers installed just for testing purposes.

Just do what I did for you in this thread. ;P
