Is there anyway to implement XOR in javascript

Question

I'm trying to implement XOR in javascript in the following way:

   // XOR validation
   if ((isEmptyString(firstStr) && !isEmptyString(secondStr)) ||
    (!isEmptyString(firstStr) && isEmptyString(secondStr))
   {
    alert(SOME_VALIDATION_MSG);
    return;
   }

Is there a better way to do this in javascript?

Thanks.

As others have pointed out, logical XOR is the same as not-equal for booleans, so you can do this:

  // XOR validation
  if( isEmptyString(firstStr) != isEmptyString(secondStr) )
    {
      alert(SOME_VALIDATION_MSG);
      return;
    }
