How to use the redis-commands.list.filter function in redis-commands

const redis = require('redis');
const commands = require('redis-commands').list;
const objectDecorator = require('./object-decorator');

const AsyncRedis = function (args) {
  const client = Array.isArray(args) ? redis.createClient(...args) : redis.createClient(args);
  return AsyncRedis.decorate(client);
};

AsyncRedis.createClient = (...args) => new AsyncRedis(args);

// this is the set of commands to NOT promisify
const commandsToSkipSet = new Set(['multi']);
// this is the set of commands to promisify
const commandSet = new Set(commands.filter(c => !commandsToSkipSet.has(c)));

AsyncRedis.decorate = redisClient => objectDecorator(redisClient, (name, method) => {
  if (commandSet.has(name)) {
    return (...args) => new Promise((resolve, reject) => {
      args.push((error, ...results) => {
        if (error) {
          reject(error, ...results);
        } else {
          resolve(...results);
        }
      });
      method.apply(redisClient, args);
    });
  }
  return method;
});
