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 a function over all values in the map.

Map a function over a NonEmpty stream.

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

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

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

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

Apply function to every element of matrix

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

toList (map f xs) = map f (toList xs)

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

toNonEmpty (map f xs) = map f (toNonEmpty xs)

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

Apply a bijection over a list using map.

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

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

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

Apply a function to all values flowing downstream

map id = cat

map (g . f) = map f >-> map g

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.

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

unstream . map f . stream = map f

O(n) map f t is the Text obtained by applying f to each element of t. Performs replacement on invalid scalar values.
