Pass object

Pass Props to a Stateless Functional Component

<App>
  <Welcome user='Mark' />
</App>

You use custom HTML attributes created by you and supported by React to be passed to the component. In this case, the created property user is passed to the component Welcome. Since Welcome is a stateless functional component, it has access to this value like so:

const Welcome = (props) => <h1>Hello, {props.user}!</h1>

Pass an Array as Props

To pass an array to a JSX element, it must be treated as JavaScript and wrapped in curly braces.

<ParentComponent>
  <ChildComponent colors={["green", "blue", "red"]} />
</ParentComponent>
