Compose a new function from smaller functions `f(g(x))`
npm install compose-function
```js import compose from 'compose-function';
const composition = compose(sqr, add2); // sqr(add2(x))
composition(2) // => 16
compose(sqr, inc)(2); // => 9 compose(inc, sqr)(2); // => 5 ```
```js import compose from 'compose-function'; import { curry, _ } from 'curry-this';
const add = (x, y) => x + y;
// add(6, sqr(add(2, x))) compose( add::curry(6), sqr, add::curry(2), );
// map(filter(list, even), sqr) compose( map::curry(, sqr), filter::curry(, even), )([1,2,3,4,5,6,7,8]) // => [4, 16, 36, 64] ```

huh?If you’re wondering what the ::
thing means, you’d better read this excellent overview by @jussi-kalliokoski or have a look at the function bind syntax proposal.
Or checkout the curry-this docs.
