This provided a good overview. The explanations were decent, but sometimes I wished for more practical application scenarios. Still, a valuable learning experience.

Hmm, I'm not sure this is for absolute beginners. It assumes a bit of prior knowledge that wasn't explicitly taught. Some examples were confusing.

The content is good, but the pace might be a bit fast for absolute beginners. I found myself rewinding quite a bit. Still valuable info.

Found it useful for a refresher. Not sure it would be the best starting point for a complete beginner, tbh.
