className vs class

[cbrake]

in the jquery-bootstrap example, I see:

// Simple pure-React component so we don't have to remember
// Bootstrap's classes
var BootstrapButton = React.createClass({
  render: function() {
    // transferPropsTo() is smart enough to merge classes provided
    // to this component.
    return this.transferPropsTo(
      <a href="javascript:;" role="button" className="btn">
        {this.props.children}
      </a>
    );
  }
});

Would class="btn" be equivalent to className="btn"? Is one preferred over the other?

@cbrake the use of class is now deprecated, check #328. There's a discussion on google groups also: https://groups.google.com/forum/#!topic/reactjs/xovHWHGHPCA

@chenglou thanks for the explanation.
