    The idea-drop part was great but missing some config during deployment, so I got an error for hard refresh. And the fullpath of error on the console should be mitigated when the user is authenticated. It would be bad showing the fullpath like that publicly for authenticated user. If Brad telling me how to hide the error this course would be 5 stars already

    The course is excellent. The projects are interesting, and the working frameworks are modern. I was able to complete all the projects and deploy them to production successfully. The explanations are clear. I highly recommend this course.

    This course is more suited as a refresher for developers with some basic background in React than for true beginners. Cons: - There are no infographics explaining the concepts and mechanisms behind React. The instructor just reads through a bullet-point list which does not teach these concepts properly. It makes it difficult for a beginner to map these concepts in his mind. - The instructor flies through the material very quickly, usually coding as he talks. This is disorienting for a beginner that doesn't have a good grasp of the subject as he needs to both learn new ideas and follow the code on screen. You will find yourself pausing and rewinding the videos numerous times to try and understand what is being said and done. This in turn repeatedly breaks your concentration and line of thought. - The instructor doesn't take into account that many of his students are NOT native English speaker. The speed at which he talks - without breathing in between - leaves non-native English speakers behind. It is extremely difficult to follow what he says. Pros: + Hands on approach - teaching through examples. + The instructor is knowledgeable. Bottom line: I recommend doing a proper React beginner course on Udemy or other platforms and then come back to this one for its strong hands-on approach.
