title: Updating an object with setState in React
body: <p>Is it at all possible to update object's properties with <code>setState</code>?</p>
  
  <p>Something like:</p>
  
  <pre><code>this.state = {
     jasper: { name: 'jasper', age: 28 },
  }
  </code></pre>
  
  <p>I have tried: </p>
  
  <pre><code>this.setState({jasper.name: 'someOtherName'});
  </code></pre>
  
  <p>and this:</p>
  
  <pre><code>this.setState({jasper: {name: 'someothername'}})
  </code></pre>
  
  <p>The first results in a syntax error and the second just does nothing. Any ideas?</p>
