Thanks for the tutorial, it's very simple and straight forward. My suggestion would be to use more meaningful databases that resemble more with real-life scenarios. E.g: (student) Name, Age, Grade, Date, etc.

this video needs an update afther Redis 5.0

Completely useless explanation and examples about scores.Completely unclear from the examples given in the tutorial that what is the role of "Score" in sorted set.Have to check official documentation for the explanation. However overall tutorial is not bad.
