-I did not create these Design Patterns. I learned from various Modern TypeScript Open Source projects, including famous ones like Zod, tRPC, Hono, elysia, and many others, as well as writing the Nammtham Framework. This process has helped me distill commonly used patterns.P.S. The image is not the book cover; it was generated by AI.
-P.S.2. The book is still in the draft phase, but you can see a rough outline.
-P.S.3. I would love to hear feedback from the community because I haven't seen anyone write about this yet, and even Western authors haven't covered it.
+Moreover, I have not seen any books or articles that cover these topics. I hope this book will help you improve your TypeScript code quality and design. I will publish the book on Leanpub. I will update the progress on X (Twitter). Please follow me on X (Twitter) [@mildronize](https://x.com/mildronize). I've been working on this book for a while, and I hope to finish it soon. I would love to hear feedback from the community because at that time when I'm writing, I haven't seen anyone write about this yet.

 ## Prerequisites
 Please make sure you have a good understanding of TypeScript before reading this book. If you are new to TypeScript, I recommend reading the [TypeScript Handbook](https://www.typescriptlang.org/docs/handbook/intro.html) first.
