I want to replace the number 1 number and the question mark ?. It can be any number. I tried the following non-working code.

questionText.replace(/[0-9]/g, '');

Very close, try:

questionText = questionText.replace(/[0-9]/g, '');

replace doesn't work on the existing string, it returns a new one. If you want to use it, you need to keep it!

Similarly, you can use a new variable:

var withNoDigits = questionText.replace(/[0-9]/g, '');

One last trick to remove whole blocks of digits at once, but that one may go too far:

questionText = questionText.replace(/d+/g, '');
