> 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

```sh

npm install compose-tiny

```

## Usage

```js

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:

```sh

🚀 16 🚀

```

## Multiple Arguments

The first function in the composition can take multiple arguments.

```js

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);

```
