compose-then

A better implementation of the "compose" FP function that allows for composing both synchronous and asynchronous functions.

Installation:

yarn add compose-then

npm install --save compose-then

Example:

import compose from 'compose-then';
 
const double = x => x * 2;
const square = x => x * x;
const plus3 = x => new Promise(resolve => setTimeout(() => resolve(x + 3), 100));
 
compose(double, square, plus3)(2)
  .then(result => // Result equals 50)
  .catch(console.error);
