-Task 1
+Task 5

+https://d17btkcdsmqrmh.cloudfront.net/node-gmp/docs/network/task
+
+We have been asked to develop a REST API for users and their hobbies. The API should have the following functionality:
+
+- Create/delete user.
+- Partially update user properties.
+- Retrieve user by id, list of users. Returns only user data, no hobbies are returned.
+- Add/delete hobby for a specific user.
+- Get a list of user hobbies.
+
+Data can be stored in memory as an array. Check the structure of User below:

+
+
+- No frameworks are used. Server is created using http module.
+- API is designed based on REST API principles. Constraints are not violated.
+- The functionality mentioned above is implemented. Proper status codes are used for responses (not only 200, but also e.g 201, 404). Input validation and authentication can be skipped.
+- Note: Try to think of modular structure for the task. Please do not have all the implementation in one file.
+
+Additional (optional tasks):
+- Caching headers are added (hint: hobbies do not change so often).
+- Hypermedia links (HATEOAS) are included (for each user to retrieve a list of hobbies).
