Michael Feathers released a whitepaper on learning a new & large code base. It provides 4 tactics in order you can use to better understand it quickly, and be productive and 3 tactics to start working. I’ve had this happen a lot, and in the past in consulting and freelance. I’ve tried a variety of techniques, so this paper is neat in that it’s way better than mine, organized, and has co-contributors.

I _do_ have a few thoughts on it as well based on using some of these.

3. How most people do NOT get how to use AWS CDK.

Learning Test Driven Development (TDD) is hard. I have a decade+ of “Test Last” “Test After” content on my blog and YouTube, none of it “Test First” until much later in my career. So here’s a 3 phase process to ease into it. I’m assuming you already know how to setup unit testing frameworks (Jest/Vitest/Mocha/Jasmine, etc) and use assertions (expect, assert, etc).
