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 a NonEmpty stream.

map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]

map (++ "x") (fromList [(5,"a"), (3,"b")]) == fromList [(3, "bx"), (5, "ax")]

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]

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

Combinator for the `<map>` element.
Example:

map $ span $ toHtml "foo"Result:

<map><span>foo</span></map>

Apply a function to all values flowing downstream

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

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.*

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

Map a function over a NonEmpty stream.
