timmywil, to your point, there are only a few places where .each is used in actual function execution, and one of them is css.js. Can we change the title to REMOVE USES OF JQUERY.EACH INTERNALLY IN FAVOR OF A FOR LOOP WHEN IMPACTING FUNCTION EXECUTION
I'll adress each point for just that example:
size: replacing jQuery.each with a for loop in getWH(), the code when gzipped and minified is one byte less.
readability: is a for loop less readable than $.each? Maybe.
maintainability: is a for loop less maintainable than $.each? Maybe.
perf: no choice but to be faster, but I'll make a perf to prove it. It might be negligible.
If the perf is negligible and the savings is only 1 byte, than perhaps $.each is more readable enough to warrant not changing.
Thanks for the response.
