The Free On-line Dictionary of Computing (19 January 2023):

map

   1.  function.

   2.  In functional programming, the most common
   higher-order function over lists.  Map applies its first
   argument to each element of its second argument (a list) and
   returns the list of results.

    map :: (a -> b) -> [a] -> [b]
    map f []     = []
    map f (x:xs) = f x : map f xs

   This can be generalised to types other than lists.
