It was a great lecture because I was able to learn more Git-related content and commands beyond just git add, commit, and push. Thanks to this, I had a fun time deploying simple side projects using GitHub Pages or Vercel. 👍👍

I've used TypeScript several times, but I was always stuck at the level of just using `type` and `interface`, so my understanding of the concepts wasn't very clear. While reading this e-book, I was able to understand not just the syntax to memorize, but why these features are necessary and what problems the type system exists to solve. In particular, the explanations are kind enough for beginners to follow, and the way concepts are built up one by one made it easy to finish the whole course without feeling overwhelmed. The examples were also appropriate, making it great to learn by typing along immediately. I would highly recommend this to frontend developers using React and TypeScript who want to solidify their foundations. Thank you for creating such a great course!

You can quickly master everything from the basics to professional layouts. It's easy to skim through HTML/CSS without a deep understanding, but this e-book was great because it firmly establishes the basic concepts that are often missed. In particular, rather than just listing theories, it is structured around hands-on practice, making it fun to learn by writing the code yourself. I used to get confused every time I tried to arrange elements on a screen, but I feel like I've learned clear standards for structuring layouts. This book will be an excellent guide for those self-studying web publishing.

There is no better book than this for grasping JavaScript concepts! I highly recommend it. I used to struggle with jumbled concepts while studying JavaScript, but this e-book points out the core essentials very clearly! Rather than just listing obvious theories, it feels like it scratches exactly where I itched by explaining why things are used this way in practice. Even complex syntax is explained in an intuitive and easy-to-understand manner, so I was able to read through it without any hurdles. I absolutely recommend this to beginners who want to build a solid foundation in JavaScript, or to anyone who wants to organize their conceptual knowledge once and for all. Thank you for sharing such great knowledge!
