I think you're at a place where you would be best off indeed pursuing other languages and solutions. Your current frustrations with Javascript will be a powerful motivation to dig into new ecosystems.

I was in a similar place once and it compelled a tour of languages that's probably the most important event in my growth as a developer.

Finally, it seems like you're talking about client-side development. Client-side applications have to manage the intersection of state, user interaction, and some interface (browser API). That interaction comes with complexity that's classically hard to manage, else we wouldn't be spinning our wheels so much trying to figure out better ones.
