title: How do I make Object.entries available in TypeScript?
body: <p>In my angular-cli-built app (which is currently using TypeScript 2.0.3) I want to be able to use this decomposition-based iterator:</p>
  
  <pre><code>for (let [key, value] of Object.entries(obj)) {
  
  }
  </code></pre>
  
  <p>What do I have to do in order to have it recognized:</p>
  
  <ul>
  <li>upgrade TypeScript?</li>
  <li>use a polyfill?
  
  <ul>
  <li>if so: how do I import it - in individual .ts files or in a config file to make it globally available?</li>
  </ul></li>
  <li>use a third-party library?</li>
  </ul>
