my two cents,

I personally buy some music from Bandcamp, and I’m pretty sure those songs don’t exist on the Apple Music catalog. So I don’t want to handle multiple apps to listen what I want.

Also, streaming platforms have the internet constraints. Sometimes, like when I’m driving, I don’t have a stable internet connection

Recompress to a lossless format (…) There is very little reason for you to do this

I though there are no reasons at all to do it. What could be a valid use case for this ?

I did a quick user script with Tampermonkey to search torrents links from torrents-csv.com of movies when I’m navigating to themoviedb.org . Not sure I can share it but it was really fun to develop and really useful for me.

For example, all of the list abstractions (map, filter, reduce, etc.) will copy the array to a new list every time you chain them.

This methods were added to generator recently. So you can avoid copying the array in memory.

All this is also without even getting started on the million JS frameworks and libraries which make it really easy to have vendor lock-in and version lock-in at the same time

In my opinion, it’s also what make JS good. There a package for almost everything.
