I’m jealous. I left Rails behind a couple years ago because I wanted to learn new things and not get stuck on a single stack. I’m currently working with Typescript/Node on a serverless framework on AWS. It’s got all the buzzwords but dear lord it’s complicated. I would not recommend it.
I find TypeScript to be an absolute god send in medium/larger projects. It's more complex to get started, but to understand and maintain it's way better.
I like Typescript a lot, especially compared to plain JS. AWS lambda, on the other hand, requires very special use cases in order to justify the complexity and learning curve, IMO. It’s not great as a general programming environment.
