    Thanks for the great tut. Firefox and W3 were giving me a headache!
    I have one question.
    In the process of delegating workers, won't that result in a slower script because we're basically increasing the lexical scope of the window object? Similar to nesting try catch statements to create dynamic scope, it helps the JS engine but not the web app.

    Hi, as you said that ajax call is on same thread, I think that is not completely true because setTimeout and Setinterval and xmlhttprequest is handled by browser in another thread and that thread push the callback function to callback queue. kindly please correct me if I m wrong. once again thanks for video 😉

    Thank you for a great video. Unfortuanely in my case worker.js with 'this' is not working, I checked in Firefox and Chrome. Removing 'this' fixed the problem. Do you know why? 'this' – context is undefined in worker.js
