Navigating the Unknown Tips for Efficiently Learning a New Codebase
summary
Suggests getting an early teammate walkthrough, mapping the code with an architecture diagram, and using a debugger to trace real execution paths; shows a concrete fix where two network calls run serially doubling load time and are parallelized to halve perceived latency, and finds and removes >500 lines from an obsolete class after spotting a leftover migration. Recommends writing onboarding docs and proposing a refactor that produces a cookie‑cutter integration pattern so other teams reuse a single approach.
