▶ [Practical Coding Book] Anyone Can Use Right Away
This book is designed to help you clone and code a movie rating web service, following the actions from start to finish.
An action is a statement that tells you exactly what command to enter, where to create a file, or what to modify.
By simply following the actions, you can create a movie rating web service with navigation, movie details, and redirection features.
In short, this book is for those who want to try making something rather than studying complex theories.

▶ A world-class [practical training structure] perfect for clone coding
This book is laid out with practical elements so that even someone who just started React yesterday can follow along comfortably.
The process of writing code and checking the results is marked with stickers, special colors, and deletion lines.
Here, the main concepts have been supplemented with Kim's explanation, and any parts that may have been missed have been emphasized again with speech bubbles to help with learning.
As you read the book, you will feel as if Nikko is right next to you, pointing and explaining things to you.

▶ [Reader First], where we put our heart and soul into every element and design that helps with learning.
- Learn React web programming by creating actual web services with your own hands.
- The useful information to know while cloning coding is supplemented by Assistant Professor Kim's explanation.
- For each chapter, we provide a 'Clone Starter Kit' that bundles the files completed in the previous chapter.
- The source code has been thoroughly verified by several experts.
- We also provide small tips such as frequently asked questions, JavaScript syntax, and reference sites.

▶ Beta Tester Reviews
Even though I'm a veterinarian by profession, it allowed me to create a movie app!
This book will help you magically create a movie app in no time, even if you don't know much about HTML, CSS, or JavaScript.
Trust me.
I also created my own movie app, Maflix, using this book.
By following this book and building a movie app, you'll gain boundless confidence that you can develop apps with React.
Lee Jun-seok, a veterinarian who studies programming as a hobby

Even a React nerd could build a movie app!
This book helped me, a React novice, create a movie app and get me started with React.
After actually building the movie app, I felt confident, thinking, "Ah! If I study this a little more, I can quickly create other apps, too."
I think it's thanks to this book that I was able to study React through clone coding.
I hope you all have the same experience! Good luck everyone! :)

It was a smooth read, unlike other computer books!
This book is written in informal language.
This is the first time I've seen informal speech used in a computer textbook.
I think it's because I'm a foreigner, but I liked it because it felt surprisingly familiar.
And it was really convenient because it clearly tells the reader what to do.
Because once you try it, it will work.
There wasn't a single part that was difficult to follow, but to fully understand the content and concepts, I think I'll need to read the book again or refer to another React book.
It was still good though.
Experiencing the entire process of developing a web application with React has been motivating and has given me an idea of ​​what I should study next. It's like looking down on Seoul from Namsan Tower.
- I happened to read Monte Cristo first.

▶ People like this will enjoy reading this
