Is it possible to improve and / or make something more correct (Bot VK)?

Question

JavaScript

Can something be done better/better here? I would be grateful for your help (I'm new)

const { VK } = require('vk-io');
const vk = new VK({ token: "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX" });
const acc = require('./acc.json');
const fs = require('fs');

function unixDate(stamp) {
    let date = new Date(stamp),
        year = date.getFullYear(),
        month = (("0" + (date.getMonth() + 1)).slice(-2)),
        day = (("0" + (date.getDate())).slice(-2))
    return `${day}.${month}.${year}`;
};

function unixTime(stamp) {
    let date = new Date(stamp),
        hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours(),
        mins = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes(),
    return `${hour}:${mins}`;
};

function getDate() {
    return unixDate(Date.now());
};
function getTime() {
    return unixTime(Date.now());
};

vk.updates.use((ctx, next) => {
  if (Number(ctx.senderId) <= 0 || ctx.senderId === undefined) return;
  if (!acc.users.find(x => x.vk === ctx.senderId)) {
    acc.number++;
    acc.users.push({
      id: acc.number,
      vk: ctx.senderId,
      nickname: 'Неизвестно',
      level: 1,
      admin: 0,
      balance: 0,
      winGame: 0,
      lossGame: 0,
      dateReg: getDate(),
      timeReg: getTime(),
    });
  };
  if (ctx.senderId < 0) return;
  return next();
});

Answer 1

1. Write the full names of the variables - account
2. VK-vk, there shouldn't be such shit code - vkToken
3. Otherwise, in my opinion, it's not bad, but at the very bottom there is not enough indentation between the lines.
