Rather than a class about TensorFlow.js, I think it would be better to think of it as a basic study of machine learning. It was a great help in studying the overall basics, but I think there are many parts that are lacking, such as the actual practice of running TensorFlow.js. There is a code, but the part where you actually learn and run it on a browser was only shown once in the last class, so if I want to use it, I think I will need to study additionally. I studied tensorflow in python, but if you approach the class with the mindset of studying it again with js as a review, I think you will be able to study satisfactorily, although there will be some regrets about the practice.
