This was an essential course for someone like me who was in the Java Spring ecosystem and suddenly found myself using React and Next.js directly. I was approaching concepts superficially and struggling without getting a grasp on various errors related to library references and builds, but it was great to learn about how the JavaScript ecosystem is structured and understand various principles by implementing them from the ground up. I think this is a perfect course to choose if you're someone who has vague anxiety while developing with JavaScript.

The lecture content is so good

I definitely feel that this lecture is different from previous ones. First, each lecture contains quite a bit of conceptual knowledge you want to convey, allowing me to build my tech stack overall. Most of all, it was great to be able to structurally understand what each practical exercise was progressively building towards. I've often worked in environments where I was the only frontend developer, but it felt like I was learning practical work by watching alongside a senior developer. If there's a series, I want to take all the lectures! I think I saw the term 'romantic JavaScript' in another review, and that word is really accurate, 👍 Thank you for creating such a good lecture.

I heard it well,
