About

Inside a Javascript function, the arguments keyword has a property callee that refers to itself. You can use this in anonymous functions to recursively call itself, or when removing event listeners.

Recursive:

function() {
	try {
		// Do something that might throw an error
	} catch (error) {
		setTimeout(arguments.callee, 0);
		return;
	}
}

Removing event handlers:

document.attachEvent("onreadystatechange", function(){
	if (document.readyState === "complete") {
		document.detachEvent("onreadystatechange", arguments.callee);
	}
});
