JSX Spread Attributes

JSX Spread Attributes

If you know all the properties that you want to place on a component a head of time, it is easy to use JSX:

  var component = <Component foo={x} bar={y} />;

petehunt / React sortable
Created December 9, 2013 22:30
Here's an example of React + jQuery UI sortable. The key thing to note is that we have the render() method do absolutely nothing and use componentDidUpdate() + React.renderComponent() to proxy updates through to the children. This lets us manage the DOM manually but still be able to use all the React goodies you know and love.
