-// This optional code is used to register a service worker.
-// register() is not called by default.
-
-// This lets the app load faster on subsequent visits in production, and gives
-// it offline capabilities. However, it also means that developers (and users)
-// will only see deployed updates on subsequent visits to a page, after all the
-// existing tabs open on the page have been closed, since previously cached
-// resources are updated in the background.
