Programming peeve of the Day

...erm, your code is not the same logic. You have inverted it.

I would never do it the same, but I can understand it as a hint and that is ok. Of course

if (condition) return;
// Do otherwhise

would be more appropriate On the other hand: Is it really worth to discuss such little things?

Whehe, that's evil :D

You're absolutely correct. Let's discuss this, instead: if (condition) { return; } else { // Do something else }

Ah ok I see you have a problem with 'if ... else' ;P [Edit] Is see in your profile "In real life, a research chemist." Yep, better stop programming. This because programming follow strict rules while chemistry has only exceptions ;P

Is snot.

if ( !condition )
{
// Do something else
}

return ;

Why? It's not as clear as to what the code will do. Plus, returning from inside an if is bad form.

I like single exit points... That code would drive me nuts too...

What's wrong with returning from inside an if? The rule about only returning at the end of a function leads to convoluted code where a flag is repeatedly used to bypass stuff just to reach the end of the function. Pure dross.

I believe to be totally proper it should be;

if ( !condition )
{
// Do something else
return;
}

return ;

As opposed to it not being clear when and where something can be returned.

You're asking if it's worth having a pointless whinge about something others do that's outside of one's control? What a silly question!

Bonus points to JSOP! I actually like having two exit points at most 1st at the very top if your initial sanity checks on input parameters fail. Get that out of the qay early 2nd at the very end of the routine.

That's what I like too. If the function is something easy... just one return at the end. If the function is something normal size... what you said. If the function is big... I do a second function to "check all needed stuff" at the beginning and then what you said.
