In React, when building components using functions instead of classes, managing state is made possible through a special function called a hook. The primary hook used for state management in functional components is the use State hook.

React JS (or simply React) is a JavaScript library used for building user interfaces, especially for single-page applications (SPAs). It was developed by Facebook and is widely adopted in web development.

Key Uses of React JS:

  1. Building UI Components
    React allows developers to create reusable UI components like buttons, forms, navigation bars, etc. This modularity makes code more organized and easier to maintain.

  2. Creating Interactive User Interfaces
    React efficiently updates and renders components when data changes. It uses a virtual DOM to optimize updates, resulting in a smooth user experience.

  3. Single-Page Applications (SPAs)
    React is ideal for SPAs where content updates dynamically without needing full page reloads (e.g., Facebook, Twitter, Gmail).

  4. Mobile App Development (with React Native)
    React concepts can be used in mobile development through React Native, enabling cross-platform mobile apps with native performance.

  5. State Management
    React handles UI state internally, and larger apps often use tools like Redux, Context API, or Mob X to manage more complex states.
