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]
