Subtyping Example App

An example of a front-end web app with subtyping/inheritance, built with plain JavaScript

This app, which is accompanied by a tutorial, is the 6th example app of our incremental sequence of six examples of Plain JS Front-End Web Apps.

This app supports the following operations:

The app supports the four standard data management operations (Create/Retrieve/Update/Delete). For playing with the app, you may first want to and then view it (e.g. by choosing "Manage books" and then "List all books").

This example app takes care of two class hierarchies:

The simple segmentation of Book into TextBook and Biography.
The segmentation of Person into Author and Employee such that Employee has a further segment, Manager.
