When you first start learning a programming language
When you haven't found a friendly coding course or book yet
When you are not a major and need to understand IT concepts

》 Systematic, repetitive learning by following the 'customized 7-step structure' that even beginners can study on their own!
This book is structured to teach the basics of programming in seven steps so that you can naturally memorize them.
Through “Key Keywords” and “Before You Begin,” we will briefly review the representative concepts of each topic in each section, and through “Speech Bubbles,” “Learning by Watching: Coding,” and “Hand Coding: Trying It Yourself,” we will naturally combine theory and practice.
In the conclusion, we will review what we have learned through [Key Points] and [Confirmation Questions].


The revised book adds steps to improve your skills through [Level Up] and [Challenge Problems], stimulating your motivation to learn.
By following the systematic structure, anyone, even someone new to programming, can learn it all the way through.

》 Two, a sense of coding that you can understand by looking at it with ‘eye coding’ and learn it properly with ‘hand coding’!
"Learning by Seeing" shows the code execution process in pictures, allowing even beginners who are just starting out with programming to understand the theory.
If you understand how the program works through 'Eye Coding', try your hand at simple code of less than 10 lines through 'Hand Coding'.
Anyone can easily learn programming through a hands-on course optimized for absolute beginners who value conceptual understanding and repetitive learning.


》 3. Video lectures to empower 'Honkong' and support for Honkong study sites & open chat with the author!
For beginners who still find it difficult to learn from books alone, we provide videos of lectures directly from the author.
You can also ask the author any questions you may have at any time through the learning site.
The author will answer your questions directly and you can also get technical information about programming.
If you want to interact with the author in real time, join the open chat and ask questions.
We also run a self-study group for readers who want to study alone but lack confidence.
With the Honkong Study Group, you can complete the course without giving up.
▶ Learning site: https://hongong.hanbit.co.kr
▶ Open chat with the author: https://open.kakao.com/o/g5rNEh7d

》 Net, [Honey Glossary] provided that can be viewed easily anytime, anywhere!
We provide a [Honkong Terminology Note] that organizes only the key concepts and terms that you must remember.
The reason why people who are new to programming find it difficult is because of the unfamiliar terminology.
Whenever you have trouble remembering a term or concept, feel free to open the [Honkong Terminology Note].
In addition to the terms presented, you can also add new terms and complete your own glossary, which will be another fun part of the process.


》 Five, NO program installation required! Online training you can do anytime, anywhere, as long as you have internet access!
You can practice anywhere, including on your laptop, mobile phone, or tablet PC, as long as you have an internet connection.
Just access your internet browser and enter the code you learned without going through a cumbersome installation process.


Who is this book for?
》 I am a complete beginner who has read programming language books but had difficulty understanding them due to lack of background knowledge.
》 Non-majors who want to try it out but have no knowledge of programming concepts
》 Non-IT workers who require programming knowledge due to the expansion of their work areas
