π‘ What is React Hydration?
Hydration is the process where React attaches event listeners and makes server-rendered HTML interactive. Hydration errors occur when the server-rendered HTML structure doesn't match what React expects to render on the client, leading to potential bugs, performance issues, and poor user experience.
