Mapcat
Raw
gistfile1.txt
(mapcat [1 2 3] [4 5 6])
=> Gives an error. Mapcat wants a function and a coll, not two colls.
(maptcat str [4 5 6])
=> Gives (\4 \5 \6). It applies the function its given to the coll its given. Then it concats the result.
(concat [4 5 6]) gives [4 5 6]. So really, mapcat is a great shortcut for accomplishing two things at once.
