Params

• properties are any rules that must be filled in

  const properties = [
      'name',
      'year',
      'publisher',
  ];

  if you plan to multiply a property for the callback

  const properties = [
      ['name', 'nama' /* alias */],
      'year',
      'publisher',
    ];

  is an object that can be obtained from the request

      name: 'Kevin Abrar Khansa',
      year: 2021,
      publisher: 'Example Inc.'
  }

• Callback

  is an output if the property is not filled

  (property) => {
      // property => name
      const message = `Failed to added. the ${property} is required.`;
      throw new Error(message);
  }
