Fundamental Concepts: Components, Props, and State
In React, components are the fundamental building blocks for user interfaces. Props allow information to be passed to components, while Stateis used to manage a component's internal dynamic data.
Key Concepts:
- Components: Functions or classes that return React elements.
- Props: Allow sending data to a component.
- State: Internal data managed by the component.
Purpose:
Understanding components, props, and state is essential for building dynamic, reusable, and maintainable React applications. These concepts form the basis for structuring interactive user interfaces.
