Some functions to allow a more functional paradigm in js

fn.js

export const compose = (...fns) =>
  fns.reduce((f, g) => (...args) => f(g(...args)));

export const pipe = (...fns) => compose.apply(compose, fns.reverse());

export const partial = (fn, [args]) => (...moreArgs) =>
  fn(...[args, ...moreArgs]);
