### compose

Performs right-to-left function composition.

Use `Array.reduce()` to perform right-to-left function composition.
The last (rightmost) function can accept one or more arguments; the remaining functions must be unary.

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

```js
const add5 = x => x + 5
const multiply = (x, y) => x * y
const multiplyAndAdd5 = compose(add5, multiply)
multiplyAndAdd5(5, 2) // 15
```
