How to make the bot respond to your message?

Question

Node.js

For example, a bot during the execution of a command sends a message (or sent it) and immediately responds to it. I already saw it in python, you need a javascript.
For example, my lines of code for the command:

client.on('message', message => {
  if (message.content === `${prefix}команда`) {
    message.channel.send(команда)
  }
})

Answer 1

message.channel.send("сообщение").then(message => message.react("реакция"))
