return <div>{props.name}</div>
}

MyComponent.defaultProps = {
name: 'John Doe'
}

displayName?: string

Used in debugging messages. You might want to set it explicitly if you want to display a different name for debugging purposes.

See

Legacy React Docs

Example


const MyComponent: FC = () => {
return <div>Hello!</div>
}

MyComponent.displayName = 'MyAwesomeComponent'
propTypes?: WeakValidationMap<CustomPropsWithChildren<object>>

Used to declare the types of the props accepted by the component. These types will be checked during rendering and in development only.

We recommend using TypeScript instead of checking prop types at runtime.
