This is useful for projects that use Typescript (e.g. a Visual Studio Code Extension).
Tested using the same logic as is present in the Patch Demo.

@NeilFraser would you review and merge this please? or do you no longer accept changes to this project?

All JavaScript is Typescript, but not the other way around. Seems better to just keep the JS version so there's less maintenance porting between two essentially identical implementations.

Since Typescript is compiled into Javascript, you would still only need to maintain one - the Typescript version.
Anyways, even if Typescript were a strict no-go, could we at least get some docstrings?
