Function composition is an act or mechanism to combine simple functions to build more complicated ones.

compose-tiny aims to provide a simple function for composition at the smallest possible size and the fasted possible speed. It's TypeScript friendly too!

Installation

npm install compose-tiny

Usage

const compose = require('compose-tiny');

const add = x => x + 2;
const sqr = x => x ** 2;

const blastOff = compose(
  x => `🚀 ${x} 🚀`
  sqr,
  add
);

blastOff(2);

Output:

🚀 16 🚀

Multiple Arguments

The first function in the composition can take multiple arguments.

const compose = require('compose-tiny');

const add = x => x + 2;
const sqr = x => x ** 2;

const blastOff = compose(
  sqr,
  add,
  (x, y, z) => (x + y) * z
);

blastOff(1, 2, 4);
