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>

Random CSS Property

mask-image

The mask-image CSS property sets the image that is used as mask layer for an element. By default this means the alpha channel of the mask image will be multiplied with the alpha channel of the element. This can be controlled with the mask-mode property.
