I thought the demo might be nicer if it used web workers to parse the grammar in the background. That way it doesn't block the DOM, so it's a bit smoother. Additionally, since we're not blocking the DOM, we can just automatically re-parse the file as the user types. I set a debounce of 700ms so that it doesn't fire too frequently. I also removed the "Generate" button entirely, and set it up so there's a little "Parsing..." message while it's parsing. I also made to sure to do a fallback if web workers aren't supported in the browser (and I tested that it works). You can try a demo [here](https://nolanlawson.s3.amazonaws.com/jison/try/index.html).
