title: Fetching scripts with an invalid type/language attributes is deprecated and will be removed
body: <p>I start to learn react.js using JSX. To use it I connect a babel library (not matter what is a version) and write a JSX code in a JS file:</p>
  
  <pre><code>&lt;script src="js/app.js" type="text/babel"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>type="text/babel" - necessarily.</p>
  
  <p>But there is a warning in Chrome:
  "Fetching scripts with an invalid type/language attributes is deprecated and will be removed in M56, around January 2017. See <a href="https://www.chromestatus.com/features/5760718284521472" rel="noreferrer">https://www.chromestatus.com/features/5760718284521472</a> for more details."</p>
  
  <p>But everything is OK, when I write a JSX code in DOM. Actually, the problem goes away without a "src=..."
  I want to write the code in JS file. What should I do for avoid a deprecation? Thank you.</p>
