Separate the string "Hello,How,Are,You,Today" by commas into an array (or list) so that each

Line 154:
s" Hello,How,Are,You,Today" s" ," split .tokens \ Hello.How.Are.You.Today

The necessary operations are unfortunately not in the standard library (yet), but simple to write:
splitBy :: (a -> Bool) -> [a] -> [[a]]
splitBy _ [] = []
splitBy f list = first : splitBy f (dropWhile f rest) where
(first, rest) = break f list
joinWith :: [a] -> [[a]] -> [a]
joinWith _ [] = []
joinWith _ [x] = x
joinWith d (x:xs) = x ++ d ++ joinWith d xs
putStrLn $ joinWith "." $ splitBy (== ',') $ "Hello,How,Are,You,Today"
=={{header|Groovy}}==
