Comment:
When creating a worker, it should be possible to assign some arguments to the
constructor, or pass an init object like so:

var worker = new Worker("someurl.js", { someData: "1234" });

The object passed could be made available as the current context
(this.someData) or as a global variable with a predefined name.

Oooh, I like this idea.

Basically it's syntax sugar for creating a worker and then posting a message to it. But it allows the data to be there while the initial worker body is running which is nice.

Comment 2 Ian 'Hixie' Hickson 2011-12-09 23:08:37 UTC

This saves like 3 lines of code, is it really that helpful?

var worker = new Worker("someurl.js");
worker.postMessage({somData: "1234"});

// someurl.js:
onmessage = function (event.data) {
  // whatever your worker would have been;
  // initial data is in event.data
}

Doesn't seem compelling. Please don't hesitate to reopen if I've missed something obvious here.
