Before we wrap up the book, I want to talk about a concept that will play a huge part in your programming career: design patterns. Googling design patterns or software programming patterns will give you a host of definitions and examples, which can be overwhelming if you’ve never encountered them before. Let’s simplify the term and define a design pattern as follows:

There’s a lot of history behind how design patterns became an integral part of the programming lexicon, but that excavation is up to you.

If this concept strikes a chord with your programming brain, start with the book Design Patterns: Elements of Reusable...
