I write Typescript for a living, and stink at swift - I don't understand where the author is coming from at all. Does Android support Typescript out of the box? Why shouldn't it as well?<p>I bundle thing into cordova and bang, what was once Typescript is now running sort of like a native app. You can make/get plugins for cordova that create wrappers for native methods, although I'm less familiar with that, but pretty sure you can expose things to the JS namespace using those techniques. Even when I'm running my typescript stuff in the browser, it's still getting transpiled before it runs there.<p>Not sure why Apple or Google would want to expose those methods via Typescript, don't know why Apple/Google would encourage Swift/Java developers to use Typescript when using Swift will create apps optimized for the hardware with fewer abstractions in the way.
