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>
