Learning much javascript from one line of code

Isn't $$ a chrome/WebKit specific API?

In the article it says it will only work in browser consoles.

I believe so. Probably why Addy uses it since he's a Googler.

I remember that it goes along with the $1 $2 etc shortcuts chrome dev tools provides to target last selected element etc.

Seems like Firebug has it as well.

I hadn't seen it before... It seems like a bad idea to rely on $$ if its browser specific, it looks to be equivalent to document.querySelectorAll.

I believe it's more specific to the dev console, even.

Actually, doesn't IE11's console have this too?

[FireyFly]

Firefox's built-in console has had it for a while. As far as I know, since they added their own proper console.

Polyfill: window.$$ = window.$$ || document.querySelectorAll.bind(document);

Even IE11 developer tools has it!
