12 React performance concepts in one infographic, from code splitting to Web Vitals

A widely shared infographic lays out 12 React performance concepts in three groups: ship less (code splitting with React.lazy, bundle budgets via analyzer, ESM-only tree shaking, AVIF images with LCP eager), free the main thread (memoize with proof via React Compiler 1.0, list virtualization, Web Workers, debounce & throttle), and load smart then measure (prefetch on intent, SSR first paint with 'use client' at the leaves, Core Web Vitals, test on real devices with throttled CPU/network). Key line: no before/after number? It's a guess.
