### `useExternalListener`
The `useExternalListener` hook helps solve a very common problem: adding and removing
a listener on some target whenever a component is mounted/unmounted. For example,
a listener on some target whenever a component is mounted/unmounted. It takes a target
as its first argument, forwards the other arguments to `addEventListener`. For example,
a dropdown menu (or its parent) may need to listen to a `click` event on `window`
to be closed:
```js
useExternalListener(window, "click", this.closeMenu);
useExternalListener(window, "click", this.closeMenu, { capture: true });
```
