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;     }
