Non-blocking functions / is recursion a good idea on arduino?

@er_name_not_found

Using recursion often wastes RAM, unless it's properly formatted and we'll designed tail-recursion

i guess recursion wasn't useful before "

@er_name_not_found

the compiler can optimize down to a simple loop

recursion can be useful, just like many things and of course needs to be implemented "properly".

my freshman 102 professor said he'd fail anyoen using "goto". make sense for the experience level of the students in the class. but "gotos" can be used "properly" to make code less complicated.

@gcjr

it would be better to explain the reasons when something is not a good idea

Everything you just said is nitpicking.

I made no absolute statement, instead I stated a correct best practice in terms that make it clear that it's a general statement.

You are arguing mastery level concepts, and doing a poor job at it, in a beginner's thread.

OP read and accepted an answer as the solution. You really haven't provided any Arduino specific counterpoint. And the reason for that is that there really isn't any. Please drop it.
