title: How to store an object in component's state?
body: <p>I make an Ajax request that returns me an object like this : </p>
  
  <pre><code>Object { user1: "darkblue", user2: "darkred" }
  </code></pre>
  
  <p>How can I store this object in the component's state since none of the following works : </p>
  
  <pre><code>this.state = { usersColors: '' } // use for strings
  this.state = { usersColors: [] } // used for arrays
  </code></pre>
  
  <p>Which syntax use for storing objects?</p>
