What can it be used for?

  It's equivalent to while (1) {...} and I've heard it referred to as a "forever" loop. It's a natural consequence of each term of the for being optional---skip the init and/or the update, and nothing happens, skip the test and it just always evaluates to true.

    It is actually a forever/infinite loop unless you break out of it with code like this: var i = 0; for (;;) { log(i); i++; if (i > 10) { break; } }; In a way is recursion, it is equivalent to this: var i = 0; (function () { log(i); i++; if (i > 10) { return; } arguments.callee(); })();
