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)) |         


        

Answer 1

Checkout this explanation of different implementations of XOR in javascript.

Just to summarize a few of them right here:

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

OR

if( isEmptyString(firstStr)? !isEmptyString(secondStr): isEmptyString(secondStr)) {
   alert(SOME_VALIDATION_MSG); 
   return;
}

OR

if( (isEmptyString(firstStr) ? 1 : 0 ) ^ (isEmptyString(secondStr) ? 1 : 0 ) ) {
   alert(SOME_VALIDATION_MSG); 
   return;
}

OR

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