Hello,

I’d like to kindly ask about using case vs. other statements/conditions.

I different languages (all OOP) I used if/else most of the time. I didn’t use case at all mainly because it needed break and I found if/elseif/elseif/elseif/else better readable.

I spent whole weekend on Elixir (great weekend! ;-)) and now I’m looking at my code and:

I used:

• case approx 50 times
• if/else 2 times for if x in some_list and if x > 0 and looking at it now I might replace it by multi-clause function
• cond 1 time for:

cond do
	n > length -> :error
	length == n -> {:ok, ""}
	true ->  {:ok, do_something_with(x)}
end

And everything else is case (not counting guard clauses/pattern matching in function arguments).

I even used case for stupid things like

case value do
    [] -> :error
    value -> {:ok, value}
end

Can anyone please tell me is this normal in Elixir or am I crazy / crazy love with case ?

P.S. this looks like funny joke question but it’s actually real and serious questions.

Kind regards,

Mat
