And yet the top js entry is above all c# and go entries. It takes the top overall on the composite score.

Not that it is representative of actual use cases. Can't use just-js in production as it's hyper optimized for this benchmark rather than a work horse. But it does provide a better view of what is possible if the work is put in.

Isn’t that just basically a js wrapper over a very optimized c++ lib though?

like bun or node or deno (Rust as well as C++).

in techempower, the vast vast majority of code running in the just-js entry is JavaScript. all the core libraries for networking and interacting with the OS are js wrappers around C++/v8. the http server, though incomplete and not production rady, is written in javascript, with http parsing handed off to picohttpparser. the postgres wire protocol is completely written in javascript. in fact, one of the advantages JS and other JIT languages have is you can optimize away a lot of unnecessary logic at run time when you need to. e.g. https://github.com/just-js/libs/blob/main/pg/pg.js#L241

the whole point of doing this was to prove that JS can be as fast as any other language for most real world web serving scenarios.

if i had more time to work on it, i am sure i could improve the fortunes score where it would be at or very close to the top of that ranking too.

Might call node.js the same thing. Deno has a rust shell and bun is zig.

Just-js had spent a lot of resources optimizing the input and output gateways to the V8 engine and it obviously pays off nicely. It does serve requests with the JS.

Is the boundary in the same place? Not familiar enough with the others to say exactly. But does it really matter?
