and not to beat a dead horse, but worker threads again wouldn't work in this exact situation even in Nodejs. They suffer from the same problems that web-workers do, meaning they use a structured copy algorithm to send data between workers (with the exception of TypedArrays), and therefore would hang the "main thread" just as long as if you did the `JSON.parse` directly in it.

It's a really annoying problem, and I'm actually really happy to see that many others have the exact same thoughts I had at the time, and that I wasn't just missing something obvious!
