React Concepts Q&A

1. What is JSX, and why is it used?

JSX is a syntax extension for JavaScript that lets you write HTML-like code in React, making it easier to create and visualize UI components.

2. What is the difference between State and Props?

State is mutable data managed within a component, while Props are immutable data passed from parent to child components[web:122][web:123].

3. What is the useState hook, and how does it work?

useState is a React hook that lets you add state to functional components by returning a state variable and a function to update it[web:123].

4. How can you share state between components in React?

Lift state up to a common parent component and pass it down as props, or use state management libraries like Context API or Redux[web:123][web:126].

5. How is event handling done in React?

Event handling in React is done by passing event handler functions as props to elements using camelCase syntax like onClick={handleClick}[web:129].
