title: NodeJS - Missing ) after argument list
body: <p>I'm using the following library:</p>
  
  <p><a href="https://github.com/leftmostcat/passport-oauth2-password-grant" rel="nofollow noreferrer">https://github.com/leftmostcat/passport-oauth2-password-grant</a></p>
  
  <p>I'm trying to implement their example:</p>
  
  <pre><code>passport.use(new PasswordGrantStrategy({
      tokenURL: 'https://www.example.com/oauth2/token',
      clientID: EXAMPLE_CLIENT_ID
  },
  function(accessToken, refreshToken, profile, done) {
      console.log(refreshToken);
  });
  </code></pre>
  
  <p>When running the application, I am getting the following error:</p>
  
  <p><code>SyntaxError: missing ) after argument list</code> </p>
  
  <p>Where is this issue coming from? I can't see there is an error in this code.</p>
