How to build a program that cannot do the wrong thing (illustrated with Typescript)

09 February 2021
With any task, how to make things work concerned me the most. Learning to do test driven development (TDD) comes a long way to help me make sure the code works as I intended - for both positive and negative examples. However, as I come across the "Representable/Valid Principle" introduced in James Koppel's Advanced Software Design Web Course, I found out that I can write code that that not just does the right thing but also can't do the wrong thing.
