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, ...]

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

map :: FoldCase s2 => (s1 -> s2) -> CI s1 -> CI s2

case-insensitive Data.CaseInsensitive

Transform the original string-like value but keep it case insensitive.

map :: (Char -> Char) -> CharSet -> CharSet

charset Data.CharSet

map :: Monad m => (a -> b) -> ConduitT a b m ()

conduit Data.Conduit.Combinators

Apply a transformation to all values in a stream. Subject to fusion

map :: Monad m => (a -> b) -> ConduitT a b m ()

conduit Data.Conduit.List

Apply a transformation to all values in a stream. Subject to fusion Since 0.3.0

map :: (Double -> Double) -> Matrix -> Matrix

Apply function to every element of matrix

map :: (a -> b) -> DList a -> DList b

dlist Data.DList

map f xs is the DList obtained by applying f to each element of xs. <math>(length (toList xs)). map obeys the law:

Fold pairs into a map.

map :: (MonadGen m, Ord k) => Range Int -> m (k, v) -> m (Map k v)

hedgehog Hedgehog.Gen Hedgehog.Internal.Gen

Generates a map using a Range to determine the length. This may fail to generate anything if the keys produced by the generator do not account for a large enough number of unique items to satify the required map size.
