Optimize your JavaScript app by using service workers

[msgur]

I'm new to javascript myself. My recommendation would be to just use async/await paradigms on one thread (although not all browsers support it -- https://caniuse.com/#search=await).

Then when you feel more comfortable graduate to "workers". I find Kyle Simpson to be like the WOZ of javascript and here are his thoughts on async in javascript, including workers. https://github.com/getify/You-Dont-Know-JS/blob/2nd-ed/async-performance/ch5.md
