Question

Is their a method to have multiple right answers with the same result?

 function check(code){
    if(code == (8 || 9 || 13 || 16 || 17 || 18 || 20 || 32)){
      return true;
    }
 }

I know I can use a switch statement, but I was wondering if their is anyway similar to this. I already tried using an array but its slow.

I also realise that you can use && but I don’t want to have to type code == a hundred times.

Answer 1

consider using an array

function check(code){
    return [8,9,13,16,17,18,20,32].indexOf(code) != -1;
}

Note that the indexOf method is a part of ECMA5 and may not be available in some browsers.
