Which do you prefer? A programming question!

I'm with all the others: first version is what I'd use. It's easier to read, more efficient, and potentially means you don't have to carry the "decision variable(s)" through to the called method.

I prefer showing logic as soon as possible *in context*. I'm also a big believer in encapsulation for the soul purpose of containing the application in edible portions.

Client-Side Type-Based Publisher/Subscriber, Exploring Synchronous, "Event-ed", and Worker Thread SubscriptionsFirst option, full stop. -but- Here's a fun little twist, if your language of choice supports this sort of thing (I'll use C# to illustrate):
void ExecuteIf(Func predicate, Action thingToExecute)
{
if (predicate())
thingToExecute();
}ExecuteIf(() => foo, DoSomething);
...but I'm not convinced that this is any easier to read, it imposes a little extra overhead, and I would still stick with your first option. Just wanted to throw it into the mix :cool:

}avoid the function call if not necessary. what you see is what it does.

However, the second might be preferable if you plan to run that bit of code a lot of times since then you just re-type one call and it makes the code easier to read.

Client-Side Type-Based Publisher/Subscriber, Exploring Synchronous, "Event-ed", and Worker Thread SubscriptionsIt depends! 1) If the section of code is executed frequently, then #2 adds the cpu overhead of the call/return therefore slowing the program down. 2) If the DoSomething code is relatively simple and is only used in this one location, then it should be coded in place in order to make readability, understandability and comprehension better. 3) If the Dosomething code is frequently used code, then #1 makes it clearer when something is done. The answer to this question is a choice of balancing performance vs readability vs understandability vs comprehension. To me, code should always be written such that I or anyone else can comprehend the intent and methodology of the original programmer in a few seconds.

What if (no pun intended), the "if" actually required more complex logic, including perhaps some nested stuff, like:
if (foo != null)
{
var data = GetSomeData(foo.SomeValue);if (data has some specific value/s)
{
DoSomething();
}
}From an aesthetic point of view, I dislike putting all that into the main method, hence why I've got a couple "Maybe..." methods because the above scenario matches in pseudo-code what I'm actually having to deal with.
