title: What means => used in this way in Javascript syntax?
body: <p>I searched something on SO and run into this, which is a way to retrive a file from your local computer and use it in browser, with AngularJS. </p>
  
  <pre><code>this.http.get(&lt;path_to_your_json_file&gt;)
   .success((data) =&gt; console.log(data));
  </code></pre>
  
  <p>I wonder what this JavaScript syntax could mean:</p>
  
  <blockquote>
    <p>(data) => console.log(data)</p>
  </blockquote>
  
  <p>I don't know if is something AngularJS specific, but I mostly doubt so. Do you know more interesting tweaks which are no so common in daily use of JavaScript?</p>
