title: Passing array to component property in React
body: <p>How can I pass an array to a component as a property. Neither of the following achieve what I am looking for. I want to pass the array of items through, manipulate them in the component and output in the render method. </p>
  
  <pre><code>&lt;List columns=['one', 'two', 'three', 'four'] /&gt; // unexpected token
  &lt;List columns="['one', 'two', 'three', 'four']" /&gt; // passed through as string not array
  </code></pre>
  
  <p>Is there a standard syntax or best practice for this kind of thing?</p>
