GET Command

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.

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.

The console will return the string Hello, Redis!, which is stored under that key.

1. What does the GET command do in Redis?

2. What happens if the specified key does not exist when using the GET command?
