 // The last4Digits variable should store the last 4 digits of cardNumber
 // However, the code isn't working
 // Before running the code, make and explain a prediction about why the code won't work
 // Then run the code and see what error it gives.
 // Consider: Why does it give this error? Is this what I predicted? If not, what's different?
 // Then try updating the expression last4Digits is assigned to, in order to get the correct value

+// I assume the code won't work because the value inside "slice()" isn't valid.
+// because we should set a valid number or 2 numbers (the first num is to set from where to start,
+// the second number is to set where to finish)
+
+// Update: after the first run of the code I realized that CardNumber is actually a number not a string.
+// so I think if I convert it into string the code will work properly. No problem with "slice()" value.
