Sounds like JavaScript and typescript would be a good fit for you. Highly expressive, dynamic and strongly typed, and highly performant both on server side and within the browser.
I do like JavaScript but it strikes a weird balance for me where it's a bit too easy to write and a bit too verbose so I tend to end up with hard to maintain code. Feels good at the start of a project but rarely a few weeks in. Also not a fan of the node ecosystem, I try to use deno where I can (maybe that would be bun these days).
