Answer 1

Pack and compress all assets that can be packed. To do this, use Webpack, Gulp, and other tools. This will reduce the number of requests to the server and increase the speed of the first page load.

Answer 2

Study Get and Set requests, these are ordinary requests from the user that require files from the site, i.e. the site gives the user additional. files(Get from user). This is fine.
Added: 304 request means successful file upload to the user. 404 - loading error
