Node JS - SyntaxError: Unexpected token

Question

I'm trying to figure out why I'm getting this unexpected token .

 Object.entries(sockets).forEach(([key, cs])) => {
     ^

SyntaxError: Unexpected token .

Object.entries(sockets).forEach(([key, cs])) => {

    process.stdout.write('\u001B[2J\u001B[0;0f'); //again clear node terminal
    const server = require('net').createServer(); // here use the createServer method from net module
    let counter = 0;
    let sockets = {};

    server.on('connection', socket => {
      socket.id = counter++; //everytime a client connects assign an id, and add to the counter for next socket Id

      //sockets[sockets.id] = socket;

      console.log('Client is connected!');
      socket.write('Hi, your name?\n');

      socket.on('data', data => {
        if(!socket[socket.id]) {
          socket.name = data.toString().trim();
          socket.write(`Welcome ... $[socket.name}!\n`);
          sockets[socket.id] = socket;
          return;
        }
       Object.entries(sockets).forEach(([key, cs])) => {
        if (socket.id == key)
          return;
        cs.write(`${socket.name}: `);
      //  console.log('data is', data);
        cs.write(data);
      });
    });

      socket.on('end', () => {
        delete sockets[socket.id];
        console.log('Client is now disconnected');
      });
    });

This is a simple chat program written in node that allows multiple clients to connect and chat among each other.

Object.entries(sockets).forEach(([key, cs]) => {}); There is extra bracket in your code — Dipak

There is not an issue of node version you put extra bracket. — Dipak

@Dipakchavda thank you! It was the extra bracket. I'm using atom editor and my eyes just became sore. It's Node 8. Again, thank you! — Stan Alam

You added an extra parenthesis in Object.entries(sockets).forEach(([key, cs]) =>{}) this line.
