good job today's honest review, Frontend Masterclass course

This is a good lecture. To leave a review, the explanations are quite lacking. For example, when explaining that arrow functions do not inherit from prototype, it would be easier to understand if the background was provided—such as the "why," why arrow functions were introduced in ES6, and what deficiencies they addressed—but such explanations are often missing. (I assume they were heavily condensed since the lecture is already quite long.) However, from a junior front-end developer's perspective, it is very helpful for drawing a "big picture" and providing keywords to expand one's thinking on various issues. I think it's good to use the lecture to experience the fact that these "forests" of unknown areas exist, and then personally study the individual "trees" within those forests by asking AI or searching on Google.
