Question

I wonder how to break a for-loop and switch-case statement at once in JavaScript?

Normally I use something like:

foo:
for(;;)
  for (;;)
      break foo;

Is there a way to do the same trick with a case at the beginning?

switch(1) {
  foo:
  case 1:
    for (;;)
      break foo;
}

Any ideas?

Answer 1

Just use the label for the switch statement itself instead of one of the cases. The break will take you out of the switch, which I think is what you’re trying to do.

foo:
switch(1) {
  case 1:
    for (;;)
      break foo;
}
