In the svelte example app there are imports like this:
import './app.css'
import svelteLogo from './assets/svelte.svg'
I could not find an explanation on the official documentation.
I am guessing that this is a svelte and not a js feature?
Which files can you import? And how do they get imported, e.g. import './app.css' applies the stylesheet and import svelteLogo from './assets/svelte.svg' appears to save the path in svelteLogo.
I searched "Svelte Import Files other than JavaScript", "js import files" and searched on https://svelte.dev/docs.
