Hello, I am new to Haskell and trying to learn it with learnyouahaskell.com and Pluralsight Haskell course. And i have a very noob question. I understand that *if .. else* is just a syntactic sugar over *case. *But what about guards then ? Are guards also *case *in different syntax ? Or vice versa ? Like with an example. anyEven nums | (length (removeOdd nums)) > 0 = True | otherwise = False anyEven' nums = case (removeOdd nums) of [] -> False (x:xs) -> True I can do the same thing with both of them. As i understand the only different thing is, with *case *i can manipulate the parameter (like here in the example i used removeOdd) and can use the manipulated parameter to decide what to do after that. So i will not need to use removeOdd function inside the case. ( maybe i will need to use in every guard definition if i choose to use guards ) Is this it? Is this the only difference between them ? And if it is, why haskell needed do implement both of them. Can't we use function like removeOdd before using it on case or guard functions ? Thanks, and sorry if my english is bad. Semih Masat
