Worker(script)

Initialize a worker with the given script.

worker.send({ string: 'world' });

Worker#send(msg, callback)

Send a request message to the worker with the given callback. When using the request/response paradigm you should pass the e.data.id property back with your response so that the correct callback may be invoked:

onmessage = function(e) {
  setTimeout(function(){
    postMessage({ id: e.data.id, value: e.data.value.toUpperCase() });
  }, 500);
};

Worker#close()

Terminate the worker.
