Doin' things with service workers

• Service workers are about giving web sites more abilities in order to operate like apps
• Big features of service workers: proxying requests / caching, receiving push notifications
• wrt. caching, most online tutorials focus solely on this feature. We won't spend time on it beyond a high level overview of how it works and why it's different from browser caching (diagram of how sw can intercept fetch requests. Could even demo)
• The more interesting feature is the ability to register for and receive push notifications, even when the page is closed
• Push notifictions can allow the app to update behind the scenes
• Do you stash the new data in IndexedDB and on initialization of the page send a message? Or can we do something different?
• Can we put the application store in the service worker?

/**
 * The range utility works like the range included in Python 3. It either takes:
 * - a single number representing the stop value (implicitly starting at 0)
 * - 2 numbers representing the start and stop values
 * - 3 numbers representing the start, stop, and step values
 *
 * @see https://docs.python.org/3/library/stdtypes.html#range
 *
 * @param {number} [start=0] - Starting number of the sequence (0 by default)
 * @param {number} stop - Generate up to but not including this number
