title: What's wrong with using <script> tags in main Layout instead of using AssetBundle in Yii PHP framework?
body: <p>I have write permission issues on my hosting account. Would it be ok to add script and link tags in the Layout file instead of using AssetBundle or registerJs?<br>
   What are the advantages and disadvantages?</p>
  
  <p><strong>EDIT:</strong><br>
  I'm using Google App Engine, without cloud storage access. Registering an Asset Bundle creates new directories which is not allowed on App Engine. I know the advantages of Asset Bundle, but my focus is on finding out if there's anything WRONG with the <code>&lt;script&gt;</code> tags, the accepted answer is perfect answer to my question. </p>
