Web Workers
I like the way you work it

The web has a problem :(
Every line of frontend JS you've ever written has (momentarily) stopped your page from working.
60 frames per second (FPS)
1000ms / 60 frames = 16.7ms
Factor in browser overhead...
WEB WORKERS!
// index.js
var worker = new Worker('worker.js');
worker.postMessage('ping');
worker.onmessage = function (e) {
console.log(e.data); // 'pong'
};// worker.js
self.onmessage = function (e) {
console.log(e.data); // 'ping'
self.postMessage('pong');
};UI thread (main thread)
Four cores
Web Workers can do...
- Ajax
- IndexedDB
- Anything JS can do
- ...but not DOM
- Virtual DOM!
