Tips on converting a Java regular expression to JavaScript regular expression

Can someone assist me in translating the Java Regex code below to JavaScript Regex?

(\\\p{Upper}{2})(\\\d{2})([\\\p{Upper}\\\p{Digit}]{1,30}+)

I attempted using the following JavaScript Regex:

([A-Z]{2})([0-9]{2})([A-Z][0-9]{1,30}+)

Unfortunately, this translation did not compile. Any suggestions or assistance would be greatly appreciated.

Answer №1

You previously separated the final [\\\p{Upper}\\\p{Digit}] into [A-Z][0-9], however, it should actually be [A-Z0-9]

Consider trying this pattern instead:

([A-Z]{2})([0-9]{2})([A-Z0-9]{1,30}+)

Another option is to substitute 0-9 with \d, like so:

([A-Z]{2})(\d{2})([A-Z\d]{1,30}+)
