Redis ZDIFFSTORE Command Explained
In Redis, the ZDIFFSTORE command computes the difference between the first and all successive input sorted sets and stores the result in the specified key.
ZDIFFSTORE works in the same way as the ZDIFF command, except that it stores the result instead of returning it (ZDIFF returns the result instead of storing it in a new key).

Redis ZRANDMEMBER Command Explained
In Redis, the ZRANDMEMBER command enables us to get one or more random elements from a sorted set.
We can specify whether or not to return only distinct elements or to allow duplicates. We can also specify whether or not to include the scores of each element in the result.
Redis ZRANGE Command Explained
In Redis, the ZRANGE command returns the specified range of elements in the sorted set stored at the specified key.
It can perform different types of range queries: by index (rank), by the score, or by lexicographical order.
Redis ZADD Command Explained
In Redis, the ZADD command is used to add one or more members to a sorted set, or to update the score for members that already exist in the sorted set.
It returns the number of elements added to the sorted set, or the number of elements updated if the CH argument is used.
