How to make the bot mention the user who told him to execute this or that command?

Question

JavaScript

I need the bot to mention the user who forced him to execute this or that command. For example, the user says: Hi, bot. You need the bot to answer: HI, (User_mention).

Answer 1

The mention looks <@user_id>
something like this, it turns out like this:

message.channel.send(`Hi, <@${message.author.id}>`)
