Calculate the maximum number of characters in the regex

Question

For example, we have the following regex:

/^[a-z]{1,10}-[0-9]{10}$/

This regex allows us to enter a maximum of 21 characters.

Is there an easy way to get number of maximum allowed characters in JavaScript?

Answer 1

No, you can't.

If you use "?" or "+" or "*" you can't guess how many characters will match.
