shorthand switch statement with conditional OR operator

Question

Is it possible to do that? For exanple for 'a' or 'b' is equal to 'X'. If 'c' or 'd' or 'e' is equal to 'Y'

var qwerty = function() {
    var month = 'a';
    var cases = {
      'a' || 'b' : month = 'X',
      'c' || 'd' || 'e' : month = 'Y'
    };
    if (cases[month]) {
      cases[month]();
    }
    return month;
};

console.log( qwerty() );

Thank you in advance :)

There is no 'or' in a switch statement, as such. But you can stack up your cases like so:

switch(month){
    case 'a':
    case 'b':
        month = 'X';
       break;
    case 'c':
    case 'd':
    case 'e':
        month = 'Y';
        break;
}
