How do I combine two lists of strings into one list of strings?

Question

For example, this:

["aaaaaa", "aaaaaa","aaaaaa"] 
["bbbb", "bbbb", "  bb"]

would go into this:

["aaaaaabbbb","aaaaaabbbb", "aaaaaa  bb"]

what did you try? do you know hoogle? HINT: the function you are looking for works like a zipper With concatenation of lists. — epsilonhalbe

You can use zipWith:

concatStrings :: [String] -> [String] -> [String]
concatStrings = zipWith (++)
