1. map :: (a -> b) -> NonEmpty a -> NonEmpty b

   base	Data.List.NonEmpty

   Map a function over a NonEmpty stream.

2. map :: (a -> b) -> [a] -> [b]

   base	GHC.Base

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

3. map :: (a -> b) -> [a] -> [b]

   base	GHC.List

   map f xs is the list obtained by applying f to each element of xs, i.e.,

   map f [x1, x2, ..., xn] == [f x1, f x2, ..., f xn]
   map f [x1, x2, ...] == [f x1, f x2, ...]
   

   this means that map id == id

   Examples

   >>> map (+1) [1, 2, 3]
   [2,3,4]
   

   >>> map id [1, 2, 3]
   [1,2,3]
   

   >>> map (\n -> 3 * n + 1) [1, 2, 3]
   [4,7,10]
   

4. map :: (Word8 -> Word8) -> ByteString -> ByteString

   bytestring	Data.ByteString

   O(n) map f xs is the ByteString obtained by applying f to each element of xs.

5. map :: (Char -> Char) -> ByteString -> ByteString

   bytestring	Data.ByteString.Char8

   O(n) map f xs is the ByteString obtained by applying f to each element of xs

6. map :: (Word8 -> Word8) -> ByteString -> ByteString

   bytestring	Data.ByteString.Lazy

   O(n) map f xs is the ByteString obtained by applying f to each element of xs.

7. map :: (Char -> Char) -> ByteString -> ByteString

   bytestring	Data.ByteString.Lazy.Char8

   O(n) map f xs is the ByteString obtained by applying f to each element of xs

8. map :: (Word8 -> Word8) -> ShortByteString -> ShortByteString

   bytestring	Data.ByteString.Short

   O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.

9. map :: (Word8 -> Word8) -> ShortByteString -> ShortByteString

   bytestring	Data.ByteString.Short.Internal

   O(n) map f xs is the ShortByteString obtained by applying f to each element of xs.

10. map :: (Char -> Char) -> Text -> Text

    text	Data.Text

    O(n) map f t is the Text obtained by applying f to each element of t. Example:

    >>> let message = pack "I am not angry. Not at all."
    
    >>> T.map (\c -> if c == '.' then '!' else c) message
    "I am not angry! Not at all!"
    

    Performs replacement on invalid scalar values.
