Ramblings
This project is deceptively simple. On the surface and in actuality it is a timer, but the important thing is that I learned about creating background processes and services for web applications. Web workers are good for heavy number crunching if you can spin up a few to do chunks of the calculation. They're good for allowing apps to function without network access if you setup a service worker, and they're good for code reuse as multiple scripts can use a shared worker.
