"Functions length should be 7-20 lines of code." - shouldn't that be "Maximum 7-20 lines of code?".
Your example functions are not 7 lines long ;)
Of course it should. Thank you :)
Well that could be simplified to "maximum 20 lines of code" if we were being all programmery about it.
Ahh but then it would all go wrong when someone puts in 0 or -1 lines of code.
and are we only allowing integers....
this is trickier than I thought ;)
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
