Documentation in legacy React code - A love/hate paradigm
summary
Claims a concrete workflow for undocumented legacy React: start by reading package.json and lock files, note the exact React version and list deprecations from the official repo, scan for mix-ins and replace mix-ins with higher‑order components, localize component state instead of hoarding it in stores, defer class→functional rewrites until after migrations, watch lifecycle hooks for deprecations, and use systematic doc reviews. Backed by npm metrics — 325,277,771 downloads between May 2019–2020 — and practical caveats about automated doc generators.
