GET [key]
- Gets the value set for the given key

SET text some text blah
- Will set the text key with value some text blah
SET user:1 { "username": "testUsername", "password": "hashedandsecrurepass" }
- Again it will set the key user:1 wit value { "username": "testUsername", "password": "hashedandsecrurepass" }
- This time however we used key user:1 because there might many users in your app
SET user:1 { "username": "testUsername", "password": "hashedandsecrurepass" } EX 60
- Exact same thing as before but this time we added EX 60 at the end so the user:1 key will expire in 60 seconds
GET user:1
- Will give you the value of user:1 key
- However if the key is expired it will return null
EXIN user:1
- Will return the time left this key has before expiration in seconds
- If already expired it will return null
- If key has no expiration set return null
DEL user:1
- Will attempt to delete the key user:1
- If deleted it will return the key name deleted back in this case it will return user:1
