Senior dev Java Scriptson joins the React team. He meets Refactor Holmes, a consulting developer and expert in legacy codebases. The two soon find themselves digging into a string of serial “regressions”.
Follow them as Holmes exposes how you can deduce technical debt hotspots, subtil change couplings, and knowledge mappings from git logs. By the end of this story, you will know how to investigate your own codebase to come up with a plan to improve code quality that could convince Scotland Yard… and probably your manager too!
