when use req.end it prints two times in console. why?

Question

I am new to Node.js

what is the use of req.end in Node.js .I use that but ,it print two times

app.use('/',function(req,res){
  res.send("hello world");  //send to browser
  console.log("by");  //print in console
  req.end;     //req is end here
}).listen(3000);

Your Using Express ? There is no function like [req.end](https://expressjs.com/en/api.html#req) — Şivā SankĂr, Feb 07 '19 at 06:01

app.use('/',function(req,res){
  res.send("hello world");  //send to browser
  console.log("by");  //print in console
  req.end;     //req is end here
}).listen(3000);

In the above code when you hit localhost:3000/ from your browser, browser hit two requests at the same time one for favicon and one for '/ ' endpoint and you create only '/' router then all request will catch in '/' route. when you hit this endpoint from postman it will print one time in the console.

solved the problem and get some knowledge on req,res – meda Feb 08 '19 at 06:42 — meda, Feb 08 '19 at 06:42
