That's exactly how the term runtime is consistently used in the JS world... not sure it's misleading at all. Certainly less exciting/ambitious than if the interpreter was also rewritten, but its what it says on the tin as I understand the words.

V8 and JSCore are a runtimes, everything else is made up stuff by people without background in compilers.

That's not at all what a runtime is, in any context, ever. Where else have you seen this solecism? It's new to me.

		> Where else have you seen this Node.js is easily the most famous example. Also deno, bun, winterjs, and probably a bunch more. Someone upthread just linked a bunch of other equivalent lua projects that also refer to themselves as runtimes: https://news.ycombinator.com/item?id=46036362 I've also seen discussions where wrapping the servo-browser-engine in a UI layer referred to the UI layer as a runtime, though I think that's a substantially less canonical use of the word than referring to the part of an implementation that takes requests from the interpreter and executes them in the surrounding environment as a runtime.
