Legacy React Docs

Example

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

MyComponent.displayName = 'MyAwesomeComponent'
Copy

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.
