In React, state and props are fundamental concepts for managing data. Here's a quick breakdown:

🔑 State

  • State is internal data that can change over time.
  • It is used to store dynamic information tied to a component.
  • Example: A counter component's current value.
  • 📌 Use useState hook to manage state in functional components.

📤 Props

  • Props are external data passed to a component.
  • They are immutable (cannot be changed within the component).
  • Example: Passing a user's name to a greeting component.
  • 📌 Use props to customize component behavior or appearance.
