It's fast and thorough. It explains the basic concepts of jQuery. However, it may be a bit overwhelming for beginners. I recommend taking the JS Basic Course and the JS Web Browser Course. Of course, there is no particularly difficult content. However, it seems that you can take the course smoothly if you know what jQuery is, why it is used, the difference between jQuery functions and jQuery objects, and what their features are. This course does not explain the concepts of jQuery functions and jQuery objects in detail. The main content is about the jQuery API. Personally, I am a person who can understand this kind of API content in a week, and I think that I should learn and use this kind of API content when I think I need it, so I quickly watched the lecture and passed it. Of course, not everyone is like me. If you are the type to organize the API step by step, you can take it slowly.
