Eta Reduce

A programming convention.

• Try and reduce the number of arguments you define in custom functions If you have a function, you can just replace the function definition with another function.

Example

vectorAdd :: Num a => [a] -> [a] -> [a]
vectorAdd v1 v2 = zipWith (+) v1 v2
vectorAdd = zipWith (+) -- eta reduce

that just calls another function, then , The programming standard to Curry a function if it works with constants.
