title: What is the TypeScript equivalent of React.PropTypes.node?
body: <p>I have searched high and low, and I can find TypeScript equivalents for everything except React's <code>PropTypes.node</code>. I know that TypeScript doesn't need any <code>PropTypes</code>, but there are some <code>PropTypes</code> that I don't know how to convert to TypeScript.</p>
  
  <p>Is it just as simple as <code>var node: any</code>? This doesn't seem right as <code>node</code> seems to have some properties. </p>
