Eliminate a Class Hierarchy and Create a Class Model
Explore how to simplify class hierarchies by applying the Class Hierarchy Merge design pattern. Learn to derive a JavaScript class model from a design model by replacing data types, adding getters and setters, and implementing validation functions to enforce attribute constraints, preparing you to build well-structured front-end applications.

Simple class hierarchies can be eliminated if we apply the Class Hierarchy Merge design pattern. The starting point for our case study is the simple class hierarchy shown in the information design model below. This hierarchy represents a disjoint (but incomplete) rigid segmentation of Book into TextBook and Biography. ...
