Ever noticed your React components re-rendering unexpectedly? It’s probably how you’re using React Context! Whenever your Context Provider's value changes—even a single property—React re-renders every component consuming that context. This isn’t selective: even components only using one piece of the context are affected. The cause? When you update state inside a Provider, React treats the new value as a different object, triggering a re-render for all context consumers via its reference check system. Understanding this can help you optimize your app's performance and avoid accidental slowdowns! 🔍
