    //一、.定义组件
    //方式1:工厂函数组件(简单组件)
    function MyComponent() {
        return <h2>工厂函数组件(简单组件)</h2>
    }

    //方式2:es6类组件(复杂组件)(通过创建MyComponent2的实例调用render方法)
    class MyComponent2 extends React.Component {
        render() {
            console.log(this);
            return <h2>es6类组件(复杂组件)</h2>
        }
    }

    //二、渲染组件标签
    ReactDOM.render(<MyComponent/>, document.getElementById('example1'));
    ReactDOM.render(<MyComponent2/>, document.getElementById('example2'));
