Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Deno vs. Bun performance is rigged
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.

Latest version of Microhttp, an event-driven, zero-dependency, pure-Java web server with 500 LOC, capable of 1,000,000+ requests per second on commodity EC2 hardware.
yes. it's mostly pure javascript though - postgres library is completely written in JS as is the http framework, which uses C++ wrapper around picohttpparser for fast http parsing. admittedly both are incomplete and need a lot of work done to make them "production ready" but JS is incredibly fast on modern engines like v8 and spidermonkey *if* you are careful about how much garbage you create and spend some time benchmarking and optimising. the C++ in just-js is minimal and mostly just simple wrappers around syscalls.

I have done a full benchmark of a POST REST API on my computer: Node.js vs Fastify vs Express.js vs Deno vs Bun vs GO. Node.js is used WITH and WITHOUT clustering on 6-core I7 processor

Bun v0.6.0 – Bun's new JavaScript bundler and minifier
i just tried recompiling v0.0.2 (https://github.com/just-js/just/releases/tag/0.0.2) of just-js and comparing it to current. for the completely static build on ubuntu 22.04 i see following:
0.0.2 (v8 v8.4.371.18) - file size: 15.2 MB, startup RSS: 8.4 MB

Is Scala to Java the same relationship as TypeScript has with ECMAScript?
Not at all. Javascript, as well as java compiled into the bytecode, but just incrementally and at the runtime. You cannot compile typescript into bytecode directly (at least it intend to be like that). You can even compile js to executable (https://github.com/just-js/just). So no, typescript transpiles to javascript, whereas scala compiles to bytecode, it's different things

A C++ web/application framework I have been building for the last 12yrs
Trust me, these guys are insane and go to really extreme levels and use optimization techniques which are not generally prevalent among the general programming fraternity. for eg, look at pico.v it is awesome and just-js is truly unbelievable, then there is faf, most of them combine low level programming trickery to reach those insane numbers. Also some of the code may not be useful in a production app but they actually extract the juice out of the metal at every instance. Memory optimizations, compiler optimizations, postgresql wire implmentations, rust black magic, these guys are really crazy and passionate.
