The React Compiler Killed Manual Optimisation. Handwriting. useMemo or useCallback is now like manual memory management. Since the v1.0 release, the compiler handles performance at build time. Write simpler code; let the toolchain optimise it.
The Rendering Debate is Dead Stop choosing one strategy per app. Hybrid rendering is now per-component. Static parts load instantly while dynamic elements stream. If you aren't mixing SSR/SSG/CSR, you’re leaving performance on the table.
Accessibility is Legally Enforced. The EAA (June 2025) made accessibility mandatory. Semantic HTML and ARIA roles are now legal requirements, not "nice-to-haves." Retrofitting costs 10x more—bake it in from day one.
TypeScript is the baseline. Plain JS is legacy. With the rise of end-to-end safety (tRPC, Zod, Drizzle), an "Architecture-First" approach is the only way to avoid quite technical debt.
AI IDEs are the Standard Success in 2026 is about the split: AI handles the boilerplate and scaffolding; you own the architecture and critical trade-offs.
The Pattern? Tools have matured. Our job is shifting from assembling frameworks to shaping product strategy. Adapt now, or fall behind the competition.
