A lazy JS implementation:

function validatePassword(password) {
  const pattern = /^[a-z0-9]{4,19}$/i;
  const test = pattern.test(password) && /[a-z]/i.test(password) && /[0-9]/.test(password);

  return test ? 'VALID' : 'INVALID';
}

function testValidatePassword() {
  console.assert(validatePassword('Username123!') === 'INVALID');
  console.assert(validatePassword('123') === 'INVALID');
  console.assert(validatePassword('Username123') === 'VALID');

  console.assert(validatePassword('Username') === 'INVALID');
  console.assert(validatePassword('IsThisPasswordTooLong') === 'INVALID');
  console.assert(validatePassword('DEVCommunity') === 'INVALID');
}
