This is not quite right. A 'break' will break out of the enclosing
'switch' statement, not only the current 'case' of it. Using it at the
end of the 'case' to exit the 'switch' (not the current 'case') is
actually probably the most common use for 'break':
switch( variable ) {
case CONSTANT1:
// ...
break; // breaks out of switch, not of current case
case CONSTANT2:
// ...
break; // breaks out of switch, not of current case
//...
}
// <<< break inside the switch jumps here
