title: How to convert key-value pair object into an array of values in ES6?
body: <p>I'm developing a React application where I need to convert a key-value object like this:</p>
  
  <pre><code>{
    0: 'John',
    1: 'Tim',
    2: 'Matt'
  };
  </code></pre>
  
  <p>To an array of just the values like this:</p>
  
  <pre><code>['John', 'Tim', 'Matt']
  </code></pre>
  
  <p>How do I accomplish this?</p>
  
  <pre><code>const obj = {
    0: 'John',
    1: 'Tim',
    2: 'Matt'
  };
  
  const arr = /* ??? */;
  </code></pre>
