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>

I believe that in order to better your knowledge base, it takes a lot of failing in order to succeed. I don't consider anything a failure as long as you get back up and you learn from your own mistakes.

sepia()

The sepia() CSS function converts the input image to sepia, giving it a warmer, more yellow/brown appearance. Its result is a <filter-function>.
