JavaScript JavaScript: Understanding cases in switch

Basically, a switch statement is a flow with three lanes, where one lane it the outer program flow, a check lane and a case lane.

A change of a lane happens with a case statement, which yields true with a strict check of the expression of the switch statement and the value of the case clause, then you go to the case lane and stays as long as you not reach either break or the end of the switch statement.

As long as you are still in the check lane, any break statement between other checks or the end does not have any effect.

code                    side  check  case  comment

                          v
switch (x) {              v >>>  v       
  case 0:                        ? >>> v   if case is true, change lane
  case 1:                        ? >>> v   if case is true, change lane
    doThis();                    v     v
  case 2:                        ? >>> v   if case is true, change lane
    doSomethingElse();           v     v
    break;                v <<<<<<<<<< .   break statement, back to program flow
  default:                v      ? >>> v   change lane if value is not in other case clauses
                          v      v
}                         v <<<  .         end of switch
