React Theme Toggle Using useState Only (Beginner Friendly)
In this video, we’ll build a simple Light/Dark Mode Toggle in React using just the useState hook.

⚠️ But we’ll also discuss the limitations of this approach — especially when your app grows or when multiple components need access to the same theme state.
