What if the user clicked "Cancel" instead of "OK"?

I run the code again and if "Cancel " clicked "null" is returned.

Is the "null" you mentioned a string?

No. Because the user didn't type or input anything

-
When you says "null" is returned, I wasn't sure if you were referring to
null(a value representing 'nothing') or a string "null". So which null was you referring to? -
The user could type/input something and then clicked "Cancel". So it is not quite correct to say "the user didn't type or input anything".

- I meant null representing nothing.
- You are right. I didn't explain it properly. The prompt didn't receive any value.
