​
MGET

Load multiple keys at once. For billing purposes, this counts as a single command. If a key is not found, it will be returned as null, so you might end up with null values in your response array. 
const values = await redis.mget("key1", "key2", "key3");

​
MSET

Set multiple values at once. For billing purposes, this counts as a single command. 
await redis.mset({
  key1: { a: 1 },
  key2: "value2",
  key3: true,
});
