What's the best way to know if the running browser supports web-workers ?

Answer 1

This is the code the script Modernizr uses:

tests[webWorkers] = function () {
    return !!window.Worker;
};

You can try window.Worker in your browser's console to check if the function exists. In your javascript code you can try this:

if (typeof(Worker) !== "undefined") {
   //great, your browser supports web workers
} else {
   //not supported
}
