The old JS interpreters were actually quite slow! That's why they made V8 in the first place. Speed was its big selling point.

- strken 5y agoOh yeah, sorry, I should have said nodejs (which has been V8 from day one) was never slow. Some of the older browser implementations were shocking. I should also add a massive asterisk to "never slow", clarifying that it's usually within a couple of orders of magnitude of compiled code, and faster than that for glue language tasks that let it call native code for the heavy lifting.
