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:\Users\ujjwa\Desktop\All Disc\Test all\index.js:236
    message.channel.send(`🏓Latency is ${m.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
                                     ^

ReferenceError: m is not defined

Can you help me out?

Answer 1

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`);
  }
});

Answer 2

client.on('message', message => {
  if (message.content === prefix + 'ping') {
  message.channel.send('Loading data').then (async (msg) =>{
    msg.delete()
    message.channel.send(`🏓Latency is ${msg.createdTimestamp - message.createdTimestamp}ms. API Latency is ${Math.round(client.ws.ping)}ms`);
  })
  }
});

I use this As My Ping Command (Sorry if I make Any Kind of Mistake, I just learned JavaScript in the last 2 Days)

module.exports={
    name:'ping',
    description: "Command ini digunakan untuk Ping",
    execute(message, args){
        message.channel.send(`🏓Latency is ${Date.now() - message.createdTimestamp}ms`);
        }
      };
