title: React JS include header
body: <p>So I'm new to React JS and currently I need some information about how to include HTML from another file to current file. For example in PHP I would have an index.php file and a header.php file. </p>
  
  <p>In header.php file I would write a html code for my page's header, and then this header would be included in index.php by doing: <code>&lt;?php include 'header.php'; ?&gt;</code></p>
  
  <p>How can I do the same with React JS?</p>
  
  <p>Having a component with <code>&lt;Header /&gt;&lt;Body /&gt;</code> just doesn't look ok to me.</p>
