     This code shows you how to connect to an Azure Cache for Redis instance using the cache host name and key environment variables. The code also stores and retrieves a string value in the cache. The `PING` and `CLIENT LIST` commands are also executed. For more examples of using Redis with the [node_redis](https://github.com/mranney/node_redis) client, see [https://redis.js.org/](https://redis.js.org/).
