Type annotations

[ariesshrimp]

I thought it might be helpful as documentation to try adding type annotations to the code base. I guess I forgot that the annotations would have to be stripped out before runtime. That sucks, because it's nice that the CLI code doesn't have any build process right now. Stripping the types would require a build step, and separate source/build directories. Or runtime overhead by stripping them dynamically.

A branch with some basic annotations is here: https://github.com/joefraley/thingssdk-cli/tree/feature/flow-types

@chalkers does it seem worth while to bother with a transpile thing, or does it seem more like useless overhead?

It feels like 'useless overhead' at the moment, but if you can do a build process then that's cool too. However, I think writing typescript definitions (tsd) for the projects generated by the CLI for the Espruino runtime is probably a better use of time surrounding types.

cool, i dunno anything about typescript. looks weird. is typescript a thing people would want to use on their embedded programs?

The type definitions are accessible in Vanilla JS so it helps with code completion. You don't actually required to use TS.
