About

The provided code defines a function called validateUKDrivingLicense, which takes a licenseNumber as input. The purpose of this function is to validate whether the given licenseNumber is a valid UK driving license number.

The function uses a regular expression (regex) to perform the validation. The regular expression pattern is as follows:

regex

/^[A-Z9]{5}\d{6}[A-Z9]{2}\d[A-Z]{2}$/

Let's break down the regular expression pattern:

• ^ and $ denote the start and end of the string, respectively. This ensures that the entire string matches the pattern.
• [A-Z9]{5} matches exactly five characters that can be uppercase letters (A-Z) or the number 9. This part represents the first five characters of the license number.
• \d{6} matches exactly six digits (0-9). This part represents the next six characters of the license number.
• [A-Z9]{2} matches exactly two characters that can be uppercase letters (A-Z) or the number 9. This part represents the next two characters of the license number.
• \d matches a single digit (0-9). This part represents the next digit of the license number.
• [A-Z]{2} matches exactly two uppercase letters (A-Z). This part represents the final two characters of the license number.

If the provided licenseNumber matches this pattern, the function will return true, indicating that the license number is valid. Otherwise, it will return false.
