Loosely Coupled Concerns and Data Structures

Over the next few screencast, we will build a mini spreadsheet clone (like Excel). The goal isn’t really to build a spreadsheet, but to show how thinking about data structures and how to represent concepts will help you separate your business logic and your UI layer.

This has many benefits:

• testability
• reveals bad decision decisions early
• performance (the wrong data structure can cost you; excessive loops, unnecessary re-renders)
