> Migrating from svelte to react, is months if not many man-years.

I’m not sure what your argument is here, but I’m pretty sure you have it backwards.

The fact that it might take a while to migrate a svelte project to react is not because of poor documentation or tooling or communication or anything like that. It’s because so many things work out of the box in svelte, and to do the same things in react would take tons of boilerplate or third party libraries. Some things may not even be possible to port, at least not easily.

This doesn’t show that svelte is bad though. It shows that react lacks functionality and is more difficult to use.
