How do you compose functions in PureScript?

Question

Tried to use (.) for function composition, but it doesn't work.

import Data.String (length, trim)

trimmedLength :: String -> Int
trimmedLength = length . trim

Answer 1

Function composition in PureScript is done with (<<<), not (.).

import Data.String (length, trim)

trimmedLength :: String -> Int
trimmedLength = length <<< trim
