for (var i = 0; i < 5; i++) {
   console.log("Outerloop: " + i);
   innerloop:
   for (var j = 0; j < 5; j++){
      if (j > 3 ) break ; // Quit the innermost loop
      if (i == 2) break innerloop; // Do the same thing
      if (i == 4) break outerloop; // Quit the outer loop
      console.log("Innerloop: " + j);
   }
