title: JavaScript: var {left, ...props} = this.props;
body: <p>I was reading the source code of Facebook's fixed-data-table, and i found <a href="https://github.com/facebook/fixed-data-table/blob/master/src/FixedDataTableCellGroup.react.js#L161" rel="noreferrer">this</a></p>
  
  <pre><code>var {left, ...props} = this.props;
  </code></pre>
  
  <p>What that it means? is this a new semantic? I'm confused o.O</p>
