完美解决 React 节流函数内存泄漏问题

import {throttle} from "lodash";

constructor(props){
    super(props)
    this.state={
        list:[]
    }
    this.showScreen = throttle(this.showScreen,1000)
}

showScreen=(e)=>{
    console.log(e)

}

componentWillUnmount = () => {
    this.showScreen.cancel();
    this.setState = (state, callback) => {
        return;
    };
}
