title: Uncaught ReferenceError: angular is not defined exception if js libraries loaded with status code 206
body: <p>In my index.html I added 2 js files. One is library file, and second is my main.js file (which has angularjs codes).</p>
  <pre><code>&lt;script src=&quot;js/lib/libraries.min.js?1599837573814&quot;&gt;&lt;/script&gt;
  &lt;script src=&quot;js/app/application.min.js?1599837573814&quot;&gt;&lt;/script&gt;
  
  </code></pre>
  <p>Sometime the library is loaded with 206 status code, then my website is broken and throws errors in Chrome console &quot;Uncaught ReferenceError: angular is not defined exception&quot;.</p>
  <pre><code>Uncaught SyntaxError: Unexpected end of input
  spectrumLib.js:1 Uncaught ReferenceError: angular is not defined
      at spectrumLib.js:1
  </code></pre>
  <p>If library file is loaded with 200 status code, it works as normal.
  What is the 206 error code and how I fix this issue?</p>
