Set TimeOut to React Function

Question

I have the following object list:

mediaList[
 {id:1, url:\"www.example.com/image1\", adType:\"image/jpeg\"},
 {id:2, url:\"www.example.com/image2\", adType:\"ima         


        

Answer 1

Don't forget to clear the timeout to prevent memory leaks:

  componentDidMount() {
    this.timeout = setTimeout(() => {
     ...
    }, 300);
  }

  componentWillUnmount() {
    clearTimeout(this.timeout);
  }
