map had to be rewritten from

const map = curry((f, arr) => arr.map(f));

to

const map = curry((f, arr) => arr.map((x) => f(x)));

This allows for partial application of each function within an array of functions.

I'd like to be able to run the tests and compute coverage for each PR.

The current curry function erases the function length which means that the function can't be re-curried to make it "safe" (for use with the Maybe monad).

The goal is to provide a way to safely compose functions without having to worry about any one of the failing.

// makeSafe :: fn -> * -> Maybe
makeSafe = (fn) => curryN(fn.length, (...args) => Maybe.of(fn(...args)));
