Typescript complains Property does not exist on ty

问题:

I am using typescript to write redux application.

var item = React.createClass({
  render: function() {
    return (<div>hello world</div>)
  }
});

export default class ItemList extends Component<any, any> {
    render() {
        return (<item />)
    }
}

Then typescript complains this:

Property 'item' does not exist on type 'JSX.IntrinsicElements'.

回答1:

var Item = React.createClass({
  render: function() {
    return (<div>hello world</div>)
  }
});

export default class ItemList extends Component<any, any> {
    render() {
        return (<Item />)
    }
}
