How to make the bot be able to find out the userid of the user and save it as a log. Discord.js?

Question

JavaScript

I want to make a moderation system for the bot but:
I want the bot to record the user ID
so that it remembers this user
I only know how to create a uid variable
let uid = client.userid;

Answer 1

Um, maybe just write the uid variable to localStorage?

let storage = window.localStorage;
let c_id = localStorage.getItem('c_id');
if(!storage.hasOwnProperty(c_id)){
//Если это новый клиент, то
storage.setItem('c_id', uid); //Записываем его в хранилище
}
