Add the specified function that

executes the

registration.

• add a registrationDate

  to the good

  thing registration object

• register the good thing object in

  the database,

• compute and return the response

  object, that in addition to the registered object, includes a field storing the

  goodthingsCount of good things now registered at the registration date.

Hint:

There is a helper function to check whether

two dates are the same date.  You need to filter the database for matching username and date pairs.

Hint:

A new date can be created

using the constructor function

Remark: For this exercise, use the Date object as per your text book, but remark that Javascript has since been updated with a new ”Temporal” object that should replace Date in future real applications.
