Checks if the bottom of the page is visible.
- Use `Window.scrollY`, `Element.scrollHeight` and `Element.clientHeight` to determine if the bottom of the page is visible.
```js
const bottomVisible = () =>
document.documentElement.clientHeight + window.scrollY >=
(document.documentElement.scrollHeight ||
document.documentElement.clientHeight);
```
```js
bottomVisible(); // true
```
