You have to implement an abstracted and simple library system.

Frame conditions

1. You have exact 2 hours of time - no minute longer.

   If you reach this time limit stop your work immediately. It is one part of the kata to respect this time limit.

2. There are no restrictions on how to use the provided time. If you want to code the entire time, take a break or a cigaret - it’s up to you.

3. This is a real world situation. You are allowed to consult the Internet, use every library you want, call a friend ...

   BUT: You are not allowed to do pair programming. AND If you have already done this kata before to have a look at your previous implementation.

4. Develop your code based on Node.js language level 8.

5. Keep the following priorities in mind while you implementing - in the mentioned order:

   1. Clean Code
   2. Loose coupling

6. Given resources:

   Hint: There is a reason why there are so many books and authors in german with umlauts.

   • authors.csv: Contains authors with its email, firstName and lastName.
   • books.csv: Contains books with its title, description, one or more authors and an isbn.
   • magazines.csv: Contains magazines with its title, one or more authors, a publishedAt and an isbn.
