Crawling pages is probably one of the most common use cases, I would imagine.

I use PhantomJS and SlimerJS to host CLI tools written in TypeScript/JavaScript. I also run these tools in the browser because I find it a better debugging experience than remote debugging.

There's a lot of functionality available through NPM and writing tools and scripts in TS can be very productive and easy to cobble things together - even advanced things.
