What I learned today — 15 February 2018

Today was mostly a day of working on tasks with a slow turn around time, which gave me renewed appreciation for Test Driven Development (TDD), where you achieve developer productivity because of the short feedback loop. Running a test gives you feedback nearly instantly, without the need to start up an application and go through some workflow. TDD keeps you in the red-green-refactor cycle without the excuse of “it’s compiling” or the time wasted by “let me just quickly check Twitter” while the app is starting up, which inevitably ends up longer than what your app took to pull itself straight.
