Thanks for this, I was also quite confused as to why the "jumping through C++" stages were so expensive. Thinking about what you've said, it makes a lot more sense that you're moving between two worlds and marshalling arguments back and forth in a variety of expensive ways. It's a shame Lin didn't explain that a little more in an otherwise excellent article, but I guess she was focussing on the JS/JIT/WASM story.
