Answer 1

change port number. Because your port is already is running.

port number like : 8000,8001,3000,3001,8080 ....

 app.listen(3030,()=>{})

(or) Kill your port number. If you are using Ubuntu OS to follow this steps.

1. To Find PID or TCP using terminal using this command: sudo netstat -ap | grep :"port number"
2. To Kill the process using this command: kill -9 "process_id or tcp_id"
3. To Run your NodeJs
