password.notOldPassword('oldpassword')  // validates to check if new password and old password are not the same

// Validate password
const { validations } = password;
console.log(validations);
// => [] all validations passed


// Non empty array means password failed validation checks
// => [ { type: 'min', message: 'The password should have min length of 8' }...]

var password = Passwordchecker('pass');

password.min(9, { message: 'This is custom message' });
// => [ { type: 'min', message: 'This is custom message' } ]
