purescript-pairs

This module defines a datatype Pair together with a few useful instances and helper functions. Note that this is not just Tuple a a but rather a list with exactly two elements. Specifically, the Functor instance maps over both values in contrast to the Functor instance for Tuple.

Example

> let point1 = 2 ^ 3
> let point2 = 4 ^ 7

> sum point1
5

> (+) <$> point1 <*> point2
(6) ^ (10)

> ("Hello" ^ "foo") <> pure " " <> ("World" ^ "bar")
("Hello World") ^ ("foo bar")
