I'm doing Maximilian's Svelte course, he puts script section at the top and it does look nice. He uses npm and only for CLI to get rollup to build and to start dev webserver. Highly recommend him and his course - on Node too.
I've taken that course too. It covers everything. The one gripe is that when it comes to Sapper, he refactors the existing pure Svelte SPA cours project, which I can't follow. Better would be a tiny program in Svelte/Sapper.
Other than that, the course is well worth the $12 for lifetime access.
