const validateGuernseyNumber = (number) => { const cleanedNumber = number.replace(/\s/g, ''); // Remove whitespace if (cleanedNumber.match(/^\+441481\d{6}$/)) { return { valid: true, type: 'landline' }; } else if (cleanedNumber.match(/^\+447[7-9]\d{2}\d{6}$/)) { return { valid: true, type: 'mobile' }; } else { return { valid: false, type: null }; } }; // Example usage: console.log(validateGuernseyNumber('+44 1481 234567')); // { valid: true, type: 'landline' } console.log(validateGuernseyNumber('+447781123456')); // { valid: true, type: 'mobile' } console.log(validateGuernseyNumber('+44 1234567890')); // { valid: false, type: null }This validation function checks the number format and identifies whether it's a landline (+44 1481) or mobile (+44 7xxx) number.
