How to Pass an Array as Props in React
If you need to pass larger amounts of information to a component you can pass in an array rather than just a single variable.
More information on the join method on the array can be found here.
Here is the basic layout:
JSX
<ParentComponent>
<ChildComponent colors={["green", "blue", "red"]} />
</ParentComponent>
HTML
<div id="challenge-node"></div>
Scripts

<script type="text/babel">
const List = (props) => {
{ /* Change code below this line */ }
return <p>{props.tasks.join(",")}</p>
{ /* Change code above this line */ }
};
class ToDo extends React.Component {
constructor(props) {
super(props);
}
render() {
return (
<div>
<h1>To Do Lists</h1>
<h2>Today</h2>
{ /* Change code below this line */ }
<List tasks={["eat", "sleep", "repeat"]}/>
<h2>Tomorrow</h2>
<List tasks={["sleep", "eat", "repeat"]}/>
{ /* Change code above this line */ }
</div>
);
}
};
ReactDOM.render(<ToDo />, document.getElementById('challenge-node'));
</script>
