title: How take out "Warning: This is an experimental feature and could change at any time" message
body: <p>Basically, I have followed
  <a href="https://stackoverflow.com/questions/31737677/vscode-is-it-possible-to-supress-experimental-decorator-warnings">VSCode: Is it possible to supress experimental decorator warnings</a> in order to take such message out but no effect has been produced.</p>
  
  <p>Firstly, I was receiving this message: </p>
  
  <blockquote>
    <p>"(node:15077) DeprecationWarning: node --debug is deprecated. Please use node --inspect instead". I read somewhere to add "protocol": "auto" in launch.json (honestly, I have no idea what I have setup to automatic).</p>
  </blockquote>
  
  <p>It changed the warning mentioned in this topic. Well, I have added jsconfig.json to the project root but it seems not change anything.</p>
  
  <p>I don't know if it is relevant but I noted that Visual Studio Code About points to Node 6.5.0 while my local Node is 7.7.4.</p>
  
  <p>At last, but not least, what does such warning mean? </p>
  
  <p>launch.json</p>
