    Great Dolly you added regex function in your javascript code, good work, keep going on.

    To fix this bug NaN :

    Try to add this line code in :

     else if (buttons[I] === equalBtn) {
firstNumber = initialNumber[0];
     //**add**
 if (isNaN(firstNumber)) {

   return counter;// initially counter=0

 }

 counter += firstNumber ;
...

    }

    You can go ahead and Try it to see if it's working to put the result to zero.

    Have a happy coding Dolly
