What's the best way to know if the running browser supports web-workers ?
is it
try { new Worker(); } catch (e) { /* it does not */ }
Thanks

A:
This is the code the script Modernizr uses:
tests[webWorkers] = function () {
return !!window.Worker;
};

A bit naive (I bet I have pages that define something called `Worker` in some of my older stuff), but...

Dive into HTML5 suggests the same code (see http://diveintohtml5.org/everything.html). @T.J.: would your thing called `Worker` end up on the `window` object though?

@Paul: Yes. If you declare a `var` at page scope, it becomes a property of `window`. My early stuff, like a lot of early stuff (and even a lot of stuff today) declared lots of `var`s at page scope. (Now I use a scoping function so most of my stuff exposes no public symbols at all.)

@T.J.: ah, right, that is awkward, I hadn‘t realised.
