password validation with regex

^                         Start anchor
(?=.*[A-Z].*[A-Z])        Ensure string has two uppercase letters.
(?=.*[!@#$&*])            Ensure string has one special case letter.
(?=.*[0-9].*[0-9])        Ensure string has two digits.
(?=.*[a-z].*[a-z].*[a-z]) Ensure string has three lowercase letters.
.{8}                      Ensure string is of length 8.
$                         End anchor.

validate password regex

// Commonly used regular expression

// Check 2-9 characters, false if not matched, true if matched
const validateName = (name) => {
   const reg = /^[u4e00-u9fa5]{2,9}$/;
   return reg.test(name);
};
// Verify phone number
const validatePhoneNum = (mobile) => {
   const reg = /^1[3,4,5,6,7,8,9]d{9}$/;
   return reg.test(mobile);
};
// Check passwords consisting of 6 to 18 uppercase and lowercase alphanumeric underscores
const validatePassword = (password) => {
   const reg = /^[a-zA-Z0-9_]{6,18}$/;
   return reg.test(password);
