I've been working on a Rails codebase for a few years now. The biggest downside coming from TypeScript codebases is that lack of static typing and the immature static typing ecosystem in Ruby. I know DHH publicly denounced strong typing, but if you're coming from a language with it, Ruby & Rails is a hard sell.
