Problem Solving with Abstraction | part 3/3

Abstraction is a very powerful tool for problem solving, and this is the final part of a shot series where I demonstrate how I implement a new feature by abstracting into something it has in common with some of the existing code. In part 1, I learnt to copy existing code and modify it - but quickly ran out of code to copy. In part 2, I learnt about handling multiple levels of abstraction, and that I should stick to a Single Level of Abstraction in all my functions. So in this part I'll clean up the code to limit the number of abstractions I have to deal with - and find a way to use abstractions to focus my effort on implementing completely new features. If you haven't watched the previous parts, start with part 1 here: https://youtu.be/nuRbPv6q2CI and find part 2 here: https://youtu.be/KQEtEPQfdjU 00:00 - Intro and recap 00:52 - Fixing the Problem 08:56 - Adding a new feature 17:06 - Completing the feature / task 23:47 - Conclusion 29:05 - Closing remarks 33:36 - Outro 🗎 Guide for Problem Solving with Abstraction: https://peterlind.dk/programming2.0/guides/problem-solving-with-abstraction.pdf This is the final part - although I do tease future videos about other aspects of abstraction - but they are far in the future.
