- Pros!!! 1. The lecture covers all the contents covered in the "Main Concepts" of the React official documentation. Rather than simply learning from the official documentation, I was able to deeply understand the necessity of each concept by learning while creating. 2. I was able to learn why this method is less recommended by using even the contents that were not mentioned in the official documentation because they were judged to be less important. 3. I was able to learn about the necessity of abstraction beyond the simple concept of React. - Not a con.. but something that was difficult during the lecture!!! 1. As someone who has a weak understanding of the MVC pattern and abstraction, when I first heard the vanilla JS part, I was shocked by the code. => The code was too difficult for me. ㅠ.ㅠ However, if you endure it and write the logic on paper and make the code your own, you will find yourself growing little by little. If you are a student who is having the same difficulties as me, if you look at the React part first and then approach the Vanilla JS part, you will be able to understand the code more easily. At least I did. - Overall!!! Honestly, I used React, but my skills were shallow, like floating on a bubble, but through this lecture, I was able to understand React more deeply. I recommend it to everyone who is starting React.
