GET Command
After storing a value in a key, it makes sense that we would want to retrieve it, and that's exactly what the GET command allows us to do.
GET [key]
Inside the [key] placeholder, you should provide the name of the key, which will return the value stored under it.
Example Usage
We already have a key called mykey, with the value Hello, Redis! stored under it. Let's retrieve the value using the key.
GET mykey
The console will return the string Hello, Redis!, which is stored under that key.
If the key does not exist, it will simply return nil.
1. What does the GET command do in Redis?
2. What happens if the specified key does not exist when using the GET command?
