What are props in React and how do they work?

Props, short for properties, are a way to pass data from parent to child components in React.

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

Sure! You can pass props like this: <ChildComponent name='John' /> and access it in the child using props.name.

What happens if I don't pass props to a component?

If you don't pass props, the component will receive 'undefined' for those props, which can lead to errors if not handled.

How do I set default props in a React component?

You can set default props using the defaultProps property on the component, like this: MyComponent.defaultProps = { name: 'Default Name' }.
