Possible error in compose example

Hi, I stumbled on this repo while learning functional programming concepts. I'm still new to this, but I believe there is a `compose` call missing:

```
const reallyAngry = compose(exclaim, (toUpperCase, moreExclaim));
```

But shouldn't it be:

```
const reallyAngry = compose(exclaim, compose(toUpperCase, moreExclaim));
```
