A todo list, storing / retrieving high scores for a very simple game... have a little fun with it. - -Your application is required to implement the following functionalities: - -- a `Server` which not only serves files, but also maintains a tabular dataset with 3 or more fields related to your application -- a `Results` functionality which shows the entire dataset residing in the server's memory -- a `Form/Entry` functionality which allows a user to add, modify, or delete (complete at least two) data items residing in the server's memory -- a `Server Logic` which, upon receiving new or modified "incoming" data, includes and uses a function that adds at least one additional derived field to this incoming data before integrating it with the existing dataset -- the `Derived field` for a new row of data must be computed based on fields already existing in the row. -For example, a `todo` dataset with `task`, `priority`, and `creation_date` may generate a new field `deadline` by looking at `creation_date` and `priority` - -Your application is required to demonstrate the use of the following concepts: - -HTML: -- One or more [HTML Forms](https://developer.mozilla.org/en-US/docs/Learn/HTML/Forms), with any combination of form tags appropriate for the user input portion of the application -- A results page displaying all data currently available on the server.
