The Worlds Most Expensive React Component & How to Stop Writing It
summary
A common greeting component becomes a cautionary tale: adding props for trailing punctuation, cute salutations, className, default styles, RTL i18n and even a component prop or polymorphic as grows into a fragile, layout‑breaking mess. The claim is that this pattern costs the industry billions of dollars. The built artifact works superficially but accumulates hacks (object rest spread, style merging, delegation) and fails; the pragmatic fix is to prefer plain functions and markup instead of one over‑generic component.
