 To connect to Redis from an application, we need a Redis client library for the language that we're coding in. Redis clients perform the following functions:
 
 - Manage the connections between our application and the Redis server.
 - Handle network communications to the Redis server using Redis' wire protocol.
-- Provide a language specific API that we use in our application.

-For Node.js, there are two popular Redis clients: ioredis and node_redis. Both clients expose similar programming APIs, wrapping each Redis command as a function that we can call in a Node.js script. For this course, we'll use ioredis which has built in support for modern JavaScript features such as Promises.
