//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‘));
