Pros
Pro Good community at present
Great community, great youtube tutorials from the the top educators. great discord community for any problem, great original online tutorial (svelte.dev).
The v3 shines and is the most adopted framework at 2020, most youtube reviewers adopt it after their review therefore increase the community hugely by their audience, Svelte is very active in development and support on github, they have kept up with all the bug fixes.
Cons
Con Not popular enough at jobs
Recently there are almost no Cons for svelte itself, except not used enough at jobs, but I see a growing statistics for Svelte jobs all the time.
It really helps organizations to save cost if they adopt it, due to being simple and declarative, well structure compared to other frameworks, it results in efficiency and continuous development benefit, when a work is passed to the next employee. Complex projects in some frameworks can't be recovered when an employee leaves, this means must do it from the scratch.
