React needs memory for its virtual DOM. Angular needs memory for bindings, subscriptions, and observables. Meanwhile jQuery just vibes with direct DOM manipulation, whistling past the graveyard of modern frontend architecture. The real joke here is that both modern frameworks are stressed about their memory footprint while jQuery is out here living its best life with zero abstractions and maximum selector chaos. Sure, your app might be unmaintainable spaghetti code, but at least you're not debugging memory leaks in a reactive state management system at 2 PM on a Friday.
