1.学习createElement的用法

class Hello extends React.Component {
  render() {
    return React.createElement('div', null, `Hello ${this.props.person}`);
  }
}


ReactDOM.render(React.createElement(Hello,{person:'amadeus'},null),
document.getElementById("root"));

其中该函数的3个参数分别对应component\props\children

2.create-react-class 模块的使用

var createReactClass=require("create-react-class");

var MyExcuse3=createReactClass({
  render: function(){
    return <h1>Hello,world!</h1>;
  }
}

);
