How to Pass Props to a Stateless Functional Component in React
Props are like properties that you can pass into a component in react.
A prop would be something like this in your component.
JSX
<div>
<MyProp id="1234" />
</div>
Then you can access it with:
JSX
const MyProp = (props) => <h1>Hello, {props.id}!</h1>
The following example passes in the current date to <CurrentDate date={Date()} />
and then accesses it with props.date <p>The current date is: {props.date}</p>
.
HTML
<div id="challenge-node"></div>
