This is a VS Code extension that will allow your Twitch chat to highlight a line of code via a command message. Example: `!line 8 server.js`. See master branch README.md for more details
For reference, here is another Twitch VS Code extension that leverages a Language Server to listen for Twitch chat messages: https://github.com/irth/twitchlint
Determine a way to thread the work for listening and parsing chat so it doesn't bog down VS Code.
