Most of the time when I use switches, I'm returning from inside the case, because I tend to pull the switch out into another function. It's usually a good idea to create a new scope with your cases, so you can avoid some irritating variable name clashes, since, unlike and if, switch cases don't automatically do that, i.e. switch(foo) { case 0: var bar = 2; // do stuff... break; case 1: var bar = 47; // error, conflicting variable name // do stuff... break; }
