What are props in React and how do they work?

Props, short for properties, are a way to pass data from one component to another in React. They allow components to be dynamic and reusable.

Can you give me an example of how to use props?

Sure! If you have a component called Greeting, you can pass a prop like this: <Greeting name='Alice' />. Inside Greeting, you can access it using props.name.

What happens if I don't pass a prop?

If you don't pass a prop, the component will receive undefined for that prop. You can set default values using defaultProps.

Are there any best practices for using props?

Yes! It's best to keep props simple, avoid passing too many props, and use prop types to validate them.
