Aspiring to be a frontend developer? Learn everything from basic to advanced JavaScript syntax 🔥

In this course, you will learn about TypeScript.

This course is a process of learning the basic theories of data structures by directly implementing them using JAVA programming. It is designed to go beyond simply learning theory, allowing you to gain a deeper understanding of the principles of data structures by implementing them with actual code. Learners will theoretically study core data structure concepts such as arrays, stacks, queues, lists, trees, and graphs, while simultaneously experiencing the actual operation process by implementing them in JAVA code. Through this, you can develop logical thinking and problem-solving skills rather than simple rote learning, and enjoy the synergistic effect of mastering both programming and data structures together. 👉 Upon completing this course, learners will master the basic concepts and structural characteristics of data structures, as well as the ability to implement and apply them in real-world development environments, building a foundation for designing more efficient and robust programs.

A course where you understand core JavaScript concepts and train to explain them verbally for interviews.

It covers machine learning concepts within the JavaScript environment. It covers the patterns and code for implementing machine learning with JavaScript and TensorFlow.js.

Learn core data structures and algorithms such as Stack, Queue, Linked List, Sorting, and DFS/BFS by implementing them directly with JavaScript. Solve frequently appearing problem types together to build problem-solving skills essential for coding tests and interviews.

If you use JS but find it difficult to explain why it works, this course provides the answer. From execution context, closures, and the event loop to Promise concurrency, prototypes, Virtual DOM, memory leaks, and bundle optimization—you won't just read about 18 chapters of advanced JS concepts; you'll learn by seeing them happen right before your eyes with a simulator. Code-based quizzes are provided for every chapter, and you can own it for life for the price of a single chicken dinner.

Build a solid foundation of skills and confidence by developing various topics from scratch with JavaScript.

Do you want to become a web frontend developer? Take your first step with a fun JavaScript course✨

This course is for those who are preparing for a coding test using JavaScript. It is designed to teach step-by-step, from fun basic problems to advanced algorithms.

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.

"Becoming a Developer Who Excels at React" has been published. This book provides a solid foundation by systematically guiding you from the basic principles of the web needed before learning React to the latest React hooks. Through over 40 diverse hands-on projects and abundant practical examples, you can apply theory directly to real-world situations and develop problem-solving skills. Additionally, it helps you grow into a developer capable of building high-quality React applications by learning essential modern web development technologies such as Redux Toolkit, Zustand, and Firebase.

Practical JavaScript Grammar for Frontend and Backend Let's finish it in one book with the #1 web book author!

The JS Core Theory and Practical Examples textbook and completed version for web publishers is a lecture manual produced in PDF format. This textbook serves to help web publishers thoroughly master the fundamentals of JavaScript and jQuery that they must know. A key feature of this manual is that it allows you to solidify theory through "Small Missions" connected to each concept. In particular, it is a well-prepared textbook that includes practical examples utilizing all the theories learned. The total PDF spans over 320 pages covering both Vanilla JavaScript and jQuery, with Coding Works adding sufficient explanations to ensure easy understanding. Notably, it allows publishers to learn essential practical jQuery interaction examples required for website production.

We have prepared this for those who want to achieve optimal results by utilizing AI, which is essential in the AI era. In just 2 hours, you can properly learn how to utilize AI through coding.

The ultimate full-stack course that teaches even beginners about web, server, mobile apps, and machine learning!! If you're not sure where to start with development, I highly recommend this course. It's all done with just Javascript!

In an era where AI writes code for us, the value of a "true architect" who can see through and control the macroscopic framework of a system becomes overwhelmingly higher. This course digs into the essence of low-level networks and TCP/UDP sockets hidden behind frameworks, cultivating the ability to design robust core engines that never crash even in the face of millions of traffic hits and large-scale data. Go beyond being a coder who blindly repeats copy-pasting, and leap forward to become an irreplaceable master who directs and controls AI with clear, system-level solutions.

This Redis course was developed in collaboration with a current Kakao interviewer. It covers hands-on practice with data structures ranging from Strings to Sorted Sets, as well as Sentinel and Cluster configuration, equipping you with the design rationale needed to excel in both technical interviews and real-world scenarios.

We will apply it in practice by crawling sites such as Naver, Amazon, Twitter, YouTube, Facebook, Instagram, and unsplash.com.

This course will help you develop the basics and practical skills of JavaScript while creating your own game program.
