how does this library work in browsers which doesn't support web worker? #14

Worker is assumed to be present and there is no feature detection, so you either polyfill it or it doesn't.

thanks!

Thankfully, Web Workers have been around for a while and are pretty broadly supported. IE10+ supports them.

If you still need to support older browsers, you can just check for the presence of window.Worker:

if (window.Worker) {
    ...
} else {
    ...
}

Might be worth adding a section noting that to the readme if anyone wants to PR!

It may also be possible to polyfill via jsdom-worker.
