What way is true?

[Yan Bernatsky]

Hello.

I have some method. What is preferable: use raise and rescue or use
return?

def(a, b)
# ...
rescue "some error" if some_is_wrong

rescue
another_method
false
end

or

def(a, b)
# ...
if some_is_wrong
another_method
false
end
end

Hello.

return?

In the example you've given, I'd use return most certainly, since you
return false either way. Exceptions are great for 'out of band'
notification of callers that something went wrong, not when the outcome
is expected and has a return value allocated for it.
