Re: [jslint] Re: Filtered for...in
You are right that votes don't make something right. It is also true that
when we are talking in the area of style, the opinion of a great quantity
professionals (or at least nontrivial enthusiasts) is of some weight. And
that you deleted your Stack Overflow account in late spring doesn't mean you
are right, either. :)
>> Since you are not wanting to exit the loop it would make more sense toplan around that condition where you do exit prematurely thereby negating
the use of continue.
This makes no sense. I don't want to *terminate* the loop (that would be
"break"). I want to go to the next invocation/cycle/loop. Why should I plan
around exiting prematurely when I don't want to do so?
>> Given the potential issues with "continue," I am not convinced thatJSLint should suggest its use, particularly when the current solution
functions perfectly well.
I am completely with you about not *suggesting* the use of 'continue'. No
one said anything about that. Instead, I asked for it to be *allowed*.
Detecting that a 'continue' does in fact filter a for...in loop is far from
promoting its use. The decision to not complain about continue was made on
jslint some time ago. Until that decision is changed, why penalize for it?
And if the decision IS changed, and the warning against the use of
'continue' is given its own option to turn it off, we'd still be in the same
position of getting an error about unfiltered for...in even though warnings
on 'continue' have been suppressed. That means to me that jslint is broken.
Filtering and the use of 'continue' are two completely separate issues. If
someone doesn't like continue, great. But for cryin' out loud, it DOES
filter a for...in loop!
>> I am happy to avoid use of "continue" unless it offers a clearimprovement. I don't see such an improvement in this case.
If you wish to avoid it, more power to you. But you also said that you agree
it's purely a stylistic consideration. Given that even though you don't
personally see a clear improvement, I do see one, so what is the harm in
allowing me my preference?
Programmers sure are an opinionated bunch (not excluding self)!
