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.

KitaJs Survey - No runtime code, fast as bare metal and top level framework.
The fastest node framework is uWebSockets (as they claim, I didn't try it yet), so if Kita's goal is to maximize performance - you should check on it.

Can the performance of the clustered nodejs application compete with (or be better than) the performance of .NET Core-6-7?
I'm serving several hundred thousands queries per second from a single nodejs server (multithreaded) with this: https://github.com/uNetworking/uWebSockets.js/

Here is a fun question:
https://github.com/uNetworking/uWebSockets.js/ ^ this is the best for performance
What are some alternatives?
When comparing just and uWebSockets.js you can also consider the following projects:
bun - Incredibly fast JavaScript runtime, bundler, test runner, and package manager – all in one
fastify-websocket - basic websocket support for fastify
fastapi - FastAPI framework, high performance, easy to learn, fast to code, ready for production
ws - Simple to use, blazing fast and thoroughly tested WebSocket client and server for Node.js
ntex - framework for composable networking services
pws - Just another simple, fast, and resilient open-source WebSockets server. 📣 [Moved to: https://github.com/soketi/soketi]
hermes - A JavaScript engine optimized for running React Native.
Socket.io - Realtime application framework (Node.JS server)
jerryscript - Ultra-lightweight JavaScript engine for the Internet of Things.
