In the rare cases we find a library that doesn't have a typescript definition, we just do: declare var Thing : any; In a global definition file. Pro tip.

In the rare cases we find a library that doesn't have a typescript definition, we just do: declare var Thing : any; In a global definition file. Pro tip. We've got a lot of mixed js and ts at the moment and when you're really lazy you can take advantage of how every object is a dictionary in js and just do something like `window["notification"]` instead of window.notification, which resolves to an 'any' type in ts. Obviously you should try and minimise that usage, but it's a useful trick to know.
