Absolutely, it's been kind of incredible progress. But it's still going to be a bottleneck more often than JS execution (in my experience at least).
Not always; I have definitely run into applications where parsing large amounts of data in code is a bottleneck, especially when building large charts. But often.
Browser vendors have done a lot of work on that over the past decade or so. It's nowhere near as slow as it was in the early days.
