JavaScript Beginner 1500 Problems E: Loops

This is a problem-solving course designed to help beginners naturally learn essential content, from basic JavaScript concepts to必須 grammar, through approximately 1500 step-by-step problems.

💡Key Points

  • Learn all beginner grammar topics through problems, including variables, conditionals, loops, and functions

  • Step by step, one problem at a time, a natural progression from concepts → application → practice

  • A practice-oriented problem book where you learn by solving problems directly rather than through concept explanations

Features of this course

📌 Over 1,500 practice problems → A practice-centered JavaScript beginner's guide where you learn concepts by solving problems. It focuses on learning by 'hands-on practice' rather than simple memorization.

📌 Each problem serves as a concept guide → Structured to help you internalize beginner syntax like conditionals, loops, and functions through examples. Rather than "learning concepts," we aim for the feeling of "concepts becoming clear as you solve problems."

📌 10% theory, 90% practice → Brief explanations followed by immediate hands-on work. Each problem is designed so you can run the code directly and verify whether it works as intended.

Hello
This is

🏫 Introduction to EduOneStep
EduOneStep is a step-by-step coding education brand
designed based on the learner's questions.

 

👨‍🏫 Instructor Introduction
I initially began teaching computer science to university students.
Gradually expanding the scope of education, I have been providing programming education for 10 years, working with a wide range of learners from 5th-grade elementary students to middle school, high school, university students, and job seekers
based on my experience.

In this process, I faced countless questions firsthand,
and I created this lecture based on the experience of organizing and accumulating those questions one by one.

 

📌 What we consider important
The most important thing I felt while conducting the classes was
“at what point the learner begins to have questions.”

We believe that the core of learning is not simply delivering content, but understanding the points where questions arise and
helping learners find the answers themselves.

 

🧩 The Beginning of EduOneStep
By organizing and accumulating questions that have repeatedly appeared over the past 10 years,
I have created content based on actual learning data..

As a result, we were able to systematically organize 1,200 problems for the beginner course alone,
and this experience also led to the publication of an online textbook (Wikidocs).

    Hong

    This course was created to solve a common problem many people face while preparing for developer jobs: "I studied CS and data structures, but I get tongue-tied during interviews." While conducting actual interviews at companies like Naver, Kakao, and Toss, I noticed that most candidates have memorized concepts but cannot explain why those concepts are necessary or how they are applied in real-world situations. Rather than simple rote memorization, this course teaches you how to understand the interviewer's intent and provide more persuasive answers to the same questions. Whether it's the OSI 7 layers, data structures, or coding tests, we focus on why you need to know them, when they are used, and how to speak about them to receive a positive evaluation in an interview. This course is for those who want to become developers who can explain what they understand in their own words, rather than just giving the same answers as everyone else.

    What Interview Officials at Kakao Tell You: Distributed Environment You Must Know

    Hong

    This course explores microservice architecture and distributed environments not as a simple list of technologies, but from a 'design perspective' required in actual work and interviews. Starting from the differences between monolithic and MSA, it progressively covers incremental migration strategies, modular monoliths, clean architecture and hexagonal architecture, clearly explaining why each choice is necessary and the trade-offs involved. Through hands-on practice, you can directly verify the intent of the structure and learn about core issues inevitably encountered in distributed environments—such as data consistency, transactions, inter-service communication, and failure handling—through realistic scenarios. Based on actual questions and perspectives from Kakao interviewers, this course aims to go beyond simple knowledge acquisition and elevate your way of thinking about distributed systems to the next level.

    This course is a practical, hands-on guide for those who want to learn how to maximize development productivity in the AI era. Beyond simply learning how to use AI, we focus on how to utilize Claude Code in a real-world development environment and how to produce "proper results." Many developers use AI but still face issues such as: ❌ Inconsistent results ❌ Poor code quality ❌ Increasing project complexity To solve these problems, this course teaches you how to utilize AI as a "development partner" rather than just a tool through: ✔ Spec-based workflows ✔ Structured command systems ✔ Sub-agent and automation strategies Furthermore, you will gain the experience of completing and deploying a full application from start to finish by integrating with real-world services such as Firebase, Figma, GitHub, and Vercel.
