Javascript switch case with array or strings

Question

At this moment I am using a switch case like this:

case 'something':
  // Do something
break;

What I would like to do is to have an array or strings like this:

case ['something', 'something too']:
  // Do something
break;

Is this possible to do?

If so how?

What is the intent , do you want to match an item in array or the array itself — Sarath Sadasivan Pillai, Feb 08 '19 at 10:15
You can use multiple case with one statement. See here => https://stackoverflow.com/questions/13207927/switch-statement-multiple-cases-in-javascript — mohiris, Feb 08 '19 at 10:16

 var aStr = ['hello','something too','something'];
 for (var i = 0; i < aStr.length; i++){
   var supp = aStr[i];
   switch (supp) {
      case 'hello':
      case 'something': 
      case 'something too':
        // Do something
        console.log('Works!')
      break;
      default:
      break;
    }
  }

You can do like this.

It can`t be done with switch construction, use if instead

if(array.includes('something' &&'something too')){
   return 'someData';
}
if(array.includes('something else')){
   return 'otherData';
}

`includes('something' &&'something too')` is really unlikely to do what you want… – Jean-Philippe Pellet Sep 29 '21 at 09:05

This should work.

var arr = ['a', 'b'];

switch (arr.toString()) {
    case arr.toString():
        console.log('ok');
}

Try This

 var my_array = ["A", "B", "C"];
     for(var i = 0; i<my_array.length;i++){
     switch(my_array[i]){
     case "A":
     console.log("It's A!");
     break;
     case "B":
     console.log("It's B!");
     break;
     case "C":
     console.log("It's C!");
     break;
     }
     }
