When it comes to my product version number, it follows the format "P.Q.R", where P, Q, and R are represented by digits. The acceptable inputs include "P", "P.Q", and "P.Q.R".
I created a regular expression that involves an OR operation.
(^\d+$) | (^\d+.\d+$) | (^\d+.\d+.\d$)
Is there a more straightforward way to write this using JavaScript?
This regular expression is effective:
^\d+(\.\d+){0,2}$
The symbol \d+ represents any quantity of digits. The expression (\.\d+) denotes a decimal point followed by any number of digits, while {0,2} specifies that the last group can repeat 0-2 times. The ^ and $ symbols mark the beginning and end of the string, ensuring that the regex matches the entire input.
