阿富汗电话号码：格式、区号和验证指南

// Regular expression patterns for validation
const patterns = {
  mobile: /^07[0-9]\s?\d{3}\s?\d{4}$/, // Allows spaces for readability
  landline: /^0[2-6][0-9]\s?\d{6}$/, // Allows spaces for readability
  international: /^\+93\s?[2-6][0-9]\s?\d{6}$/ // Allows spaces for readability
};

// Example validation function
function validateAfghanPhone(number, type) {
  const cleanedNumber = number.replace(/\s/g, ''); // Remove spaces before validation
  return patterns[type].test(cleanedNumber);
}

// Example formatting function (Mobile)
function formatAfghanMobile(number) {
  const cleanedNumber = number.replace(/\s/g, '');
  if (!patterns.mobile.test(cleanedNumber)) {
      return "Invalid Number"; // Or throw an error
  }
  return cleanedNumber.replace(/(\d{3})(\d{3})(\d{4})/, '$1 $2 $3');
}

// Example formatting function (Landline)
function formatAfghanLandline(number) {
  const cleanedNumber = number.replace(/\s/g, '');
  if (!patterns.landline.test(cleanedNumber)) {
      return "Invalid Number"; // Or throw an error
  }
  return cleanedNumber.replace(/(\d{2})(\d{3})(\d{3})/, '$1 $2 $3');
}

// Example conversion to international format
function toInternationalFormat(number) {
  const cleaned = number.replace(/\s/g, '').replace(/^0/, '');
  return `+93 ${cleaned}`;
}


// Example usage
console.log(validateAfghanPhone("079 123 4567", "mobile")); // true
console.log(formatAfghanMobile("0791234567")); // "079 123 4567"
console.log(toInternationalFormat("020 123456")); // "+93 20 123456"

// Example test case where validation might fail (incorrect prefix)
console.log(validateAfghanPhone("080 1234567", "mobile")); // false - handles incorrect prefix

// Example test case where formatting needs adaptation (international number)
console.log(formatAfghanMobile("+93201234567")); // "Invalid Number" - demonstrates need for adaptation for international numbers.  You would need to use a different formatting function or adapt this one.
