To a limited capacity. If you're looking for: console.log('this is in the document'); go(function() { console.log('this is in a web worker'); }); I'd recommend against it. Even if you can toString() the function passed to go() and load that into a worker, you'd not carry the function's closure, which I think is too complex. var x = 5; go(function() { console.log('x = '+x); }); // => x = undefined Could be done, but I'd rather stick with paradigms that fit the language more closely.
