The above example validate 5 digit (eg-12344) or 5 digit-4 digit (eg- 12345-2323) zip code



by using regular expression- /^\d{5}([-]\d{4})?$/

Here /../(forward slashes) is used to quote your regular expression.

^ shows beginning of string.

\d{5} is for any digit 0-9 having 5 places.

() is used for grouping content.

[-] is used to put -.



\d{4} having sequence of digits of 4 places.

$ is used for ending the string.

test() method takes one argument and check that to the pattern.
