I used console.log to display a port number but it not working.It displaying string but when i use this with value it not displaying.
const http = require('http');
const express = require('express');
const socketio = require('socket.io');
const PORT = process.env.PORT || 5000;
const app = express();
const server = http.createServer(app);
const io = socketio(server);
server.listen(PORT,()=>{
return console.log('server has started on port ${PORT}');
});
I m getting Following: Output:server has started on port ${PORT}
You are using it wrong. You must use backticks - ` and not quotes - '
So the correct format is -
server.listen(PORT,()=>{
return console.log(`server has started on port ${PORT}`);
});
${}
and then output the evaluated value.Hope this solves your issue !
Wrong quotes
Use ``
console.log(`server has started on port ${PORT}`);
