javascript - Discord.js Ping Command

Question

I was trying to make a ping command for my bot here is my Code

client.on('message', message => {
  if (message.content === '+ping') {  
    message.channel.send(`??Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  }
});

However I end up getting the following error

C:UsersujjwaDesktopAll DiscTest allindex.js:236
    message.channel.send(`??Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
                                     ^

Can you help me out?

You need to use Date.now() - message.createdTimestamp to get the latency.

client.on('message', message => {
  if (message.content === '+ping') {  
    message.channel.send(`??Latency is ${Date.now() - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  }
});
