The Worlds Most Expensive React Component
summary
A live code walkthrough starts with a tiny hello message component and adds a trailing punctuation prop, a salutation default, className spreading, an as prop for polymorphic tags, a delegated style function, and children for i18n, showing step‑by‑step how each quick fix accumulates API cruft, breaks styling, and forces hacks to remain backward compatible; concludes that the real cost is collaborative — repeated rewrites, cross‑team friction, and lost hours — and argues for composition and organizational change instead of ever‑growing components.
