React高阶组件的使用浅析

function Goods(props) {
    console.log(props);
    return (
        <div className="box1">
            <h3 style={{color:props.color}}>Hello Js</h3>
        </div>
    )
}
//高阶组件的代码， 属性代理的方式
function Color(WrapperComponent){
    return class Color extends React.Component{
        render(){
            console.log(this.props)
            let obj = {color:"#0088dd"}
            return (
                <WrapperComponent {...this.props} {...obj}/>
            )
        }
    }
}
export default Color(Goods);
