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.

Is it really a good idea to use Node.js for server-side JavaScript?
GraalVM is a Java VM and JDK that also has an ecmascript compliant JavaScript implementation. Check out es4x.

Why Is JavaScript in the Top of TechEmpower Web Framework Benchmarks? Just(JS)
Also, shoutout to es4x [1] that is similarly high up in the charts.

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
https://github.com/just-js/just Is another for a V8 runtime, it really shows how well optimized it is. https://www.techempower.com/benchmarks/#section=data-r21

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.
