I probably would have pushed for Hono as the underlying framework... That said, I've been a fan of Koa/Oak over Express for a very long time. For API usage, the swagger+zod integration is pretty decent, though it changes the typical patterns a bit.
All-in, there's no single silver bullet to solving a given issue. Python has a lot of ecosystem around it in terms of integrations that you may or may not need that might be harder with JS. It really just depends.
Glad your migration/switch went relatively smoothly all the same.
It depends on your use case. Exactly. If you’re building big data intensive pipelines with lots of array manipulation or matrix multiplications you know what will shine. Building user facing APIs, use something with types and solid async.
Matching your latter definition, I'd be inclined to go with Rust or C#... that said, you can go a long way with TS in Node/Deno/Bun/Cloudflare/Vercel, etc.
