## Live Chat

The library's Live Chat parser and poller were heavily based on YouTube's original compiled code, this makes it behave in a similar if not identical way to YouTube's Live Chat. Here you can do all sorts of funny things, ex; track messages, donations, polls, and much more.

## Usage 

Before fetching a Live Chat, you have to retrieve the target livestream's info:

```js
const info = await yt.getInfo('video_id');
```

Then you may request a Live Chat instance:
```js
const livechat = await info.getLiveChat();
```
