Checks if the bottom of the page is visible.
|
|
|
|
- Use `scrollY`, `scrollHeight` and `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
|
|
```
