I'm curious if Node/JavaScript developers would appreciate an SDK having been written in TypeScript, even if only wanting to use the transpiled JavaScript. My inclination is the additional type checking would be appreciated and help save developers from odd mistakes of data type being passed back from the SDK.

I know its a little extra overhead and adds a bit to the package size, but would you use it? (For context, this would be an SDK for interacting with a RESTful API).
