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>
