Delete 2nd to last message.

[Syntast1c]

I have a command system which looks like this: if(msg.content == '.commandname' && msg.author.id == client.user.id){ //code } I want it to delete the part where the user types .commandname, I am new to this so if anyone minds helping me that would be appriciated.

if(msg.content == ".commandname" && msg.author.id == client.user.id) {
  msg.delete(); // this will remove the msg that's content is ".commandname"

  msg.channel.send("test") // this will then send a new message to the same channel with the message "test"
}
