What can I say? We’re a team of hackers. It’s not our goal to solve every problem immediately, just the ones facing us and our developers today. We wanted an abstraction simple enough to ship to our community and customers but robust enough, conceptually, to be built out into a fully expressive language. (Hence FaaSlang.)

ESDoc is JavaScript specific, but the concept of relying on comments to infer types is not, nor is the JSON format we store function execution information in. :)

(Well, I mean, we rely on JavaScript-translatable types — but can create parallels to other runtimes and languages.)
