there are underlying differences between C++, Rust, JS. The aim of libraries are re-usability. To call a small library shallow, its your choice. If you want to drag a helpers folder with you anywhere its your choice. JS does not have the fate to have language updates as C, Rust. Code lives in many envoirements and is in many cases polyfilled/transpiled.

You are welcome to shape your point of view in this free world.

Checkout slidevjs, that may also look shallow to you. The eco-system is very open. It will never be as C++ or Rust. I believe everyone is happy where they are.
