 Let's define a `listener.js`, which starts a TCP server on port 9999 and waits for a connection. Once we get a connection, we wait for a stream. And finally, once we have the stream, we pull the data from that stream, and printing it to the console.
 
 ```JavaScript
-const multiplex = require('libp2p-multiplex')

 const tcp = require('net')
 const pull = require('pull-stream')
 const toPull = require('stream-to-pull-stream')
 
 const listener = tcp.createServer((socket) => {
   console.log('[listener] Got connection!')

 Now, let's define `dialer.js` who will connect to our `listener` over a TCP socket. Once we have that, we'll put a message in the stream for our `listener`.
