How do I manage state in React applications?

Asked on Sep 13, 2025

Answer

Managing state in React applications can be done using various methods, such as using React's built-in state management with hooks like useState and useReducer, or by using external libraries like Redux for more complex state management needs.

// Using useState for simple state management
        import React, { useState } from 'react';

        function Counter() {
            const [count, setCount] = useState(0);

            return (
                <div>
                    <p>Count: {count}</p>
                    <button onClick={() => setCount(count + 1)}>Increment</button>
                </div>
            );
        }

        export default Counter;

Additional Comment:

The code demonstrates the use of the "useState" hook to manage a simple counter state in a functional component.
"useState" initializes the state with a value of 0 and provides a function "setCount" to update the state.
The "Increment" button updates the state by calling "setCount" with the new value.
For more complex state management, consider using "useReducer" or external libraries like Redux or Context API.
Always ensure state updates are done in a way that React can efficiently re-render components.
