i have a 'for' loop
and inside of him an 'switch' loop.
but the switch loop executes just ONCE.
why? and how can i make it executable as many time as i want to?

example:

for(let i = 0; i < 5; i++){

switch(something[i]){
case 1:
alert("case 1 has been activated!");
break;
case 2:
alert("case 2 has been activated!");
break;
}

A switch statement is not a loop. Moreover, if what is at something[i] is not 1 or 2, nothing will be excuted and will silently pass.
You will have to put a breakpoint on the for line and debug line by line to see what is going on.
You may want to add a default case to account for unanticipated values:

C#

switch (something[i]) {
   // ...
   default:
      alert("unexpected value: " + something[i]);
      break;
}

Probably because a switch is not a loop. You need to learn the language structures, we can't fo it for you.
