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.

We deal with ideas. You can logically organize the core and fundamentals of JavaScript. You can structure your own JavaScript experiences and thoughts. You can establish the technical logic of JavaScript. You can broaden your perspective to see the entirety of JavaScript. You can prepare for JavaScript technical interview questions.

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

Recommended for those who want to acquire their own skills and learn web development step-by-step. We teach from the history of web browsers and languages.

Algorithms seem so difficult... Even students who are not good at math can finish the basics of algorithms in one go with this class! We will teach you the basic concepts needed to solve algorithms step by step, and even Codecamp's know-how on applying them to problems :)

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 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.

Apps play an important role in our daily lives. However, the process of developing and maintaining native apps is long and complex, and can be quite costly. This course introduces Progressive Web Apps (PWA), an alternative that has been gaining attention as of September 2024. PWA combines the advantages of web technology and native apps, enabling faster and more efficient app development and maintenance. Through hands-on practice, you'll learn the concepts, advantages, and implementation methods of PWA step by step, and develop the skills to apply them directly in real-world scenarios.

In many programming languages, including Javascript, asynchronous operations are one of the most difficult and complex elements of software. You can discard primitive asynchronous programming such as setTimeout and setInterval and easily handle complex asynchronous operations through RxJS.
