RegEx Description
^ The password string will start this way
(?=.*[a-z]) The string must contain at least 1 lowercase alphabetical character
(?=.*[A-Z]) The string must contain at least 1 uppercase alphabetical character
(?=.*[0-9]) The string must contain at least 1 numeric character
(?=.*[!@#$%^&*]) The string must contain at least one special character, but we are escaping reserved RegEx characters to avoid conflict

Explanation:
^ // start of input
(?=.*?[A-Z]) // Lookahead to make sure there is at least one upper case letter
(?=.*?[a-z]) // Lookahead to make sure there is at least one lower case letter
(?=.*?[0-9]) // Lookahead to make sure there is at least one number
[A-Za-z0-9]{6,} // Make sure there are at least 6 characters of [A-Za-z0-9]
$ // end of inputjavascript password validation regex test

const re = new RegExp("^(?=.*[a-z])(?=.*[A-Z])(?=.*[0-9])(?=.*[!@#\$%\^&\*])(?=.{8,})");
