Module development and code questions

Does anyone know why? thank you very much!

We are using Drupal CMS to store the multilingual content and its served through custom APIs. We have a CMS GUI for content authors where they can view, search, filter, translate, add, edit and delete the content.

Drupal 10 is like a continuous and duuuuull pain...

To install drupal 10 you must conceive the Composer; after doing that, you solve, how to enable video.js to play videos.

I do not know, how to use npm-asset.

Are you serious about making drupal 10 like the Quest?!?
