Freeze variable in closure

Raw

To make closures inside loops a little more descriptive:

for(var i = 0; i < 5; i++) {
  freeze(i, function(i) {
    setTimeout(function() {
      console.log(i);
    }, 1000);
  });
}

Raw

freeze_closure.js

	function freeze() {
	var args = Array.prototype.slice.call(arguments);
	return args.pop().apply(this, args);
	}
