If you want to understand TypeScript properly, you should read the official documentation at least once, right? This lecture will convey only the important parts of the documentation in an easy-to-understand manner, and also teach you the content you need in practice!

We will teach you everything from basic concepts to situational test writing methods and advanced testing knowledge so that you can master everything about front-end unit testing.

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.

HTML+CSS+JS Practical Portfolio (Season 3) is a process of creating practical publishing examples. Through the creation of various practical examples, you can grow your publishing skills to an intermediate-to-advanced level. With over 34 hours of ample lecture time and various types of practical creation processes, you can fully master production know-how and application methods.

This is a full-stack series course aimed at developing web and app services at a commercially viable level for beginners, based on real-world experience developing web services in the field. As Part 2 of this series, this course thoroughly covers the latest HTML5, CSS3, and vanilla JavaScript + ES6, considering responsiveness and compatibility among the various frontend technologies available.

This course is not about "Let's build something amazing with the latest technology," but rather the most practical web development beginner course that makes you feel "You can build it yourself with just a little knowledge." We'll create the basic structure with HTML and JavaScript, exchange data using Node.js and SQLite, and complete a simple web page with Next.js. We minimize complex configurations and difficult theories, and focus on getting a hands-on feel for web development flow by writing code that actually works. This course centers on 'hands-on experience' rather than just 'learning.' If you've touched code even a little bit, anyone can follow along and feel the satisfaction of completion.

This course is a series of courses on functional programming and JavaScript ES6+, covering a variety of application cases.

The ES6+ Understanding Course provides an in-depth introduction to the ES6 and subsequent standard ECMAScript specifications for JavaScript, with a theoretical foundation, and explains the differences from ES5, as well as the concepts and operating principles.

This lecture is an introductory NodeJs course that even those new to programming can confidently take. NodeJs is a technology that allows JavaScript, which originally only ran within web browsers, to be used on PCs or servers. Currently, it is being utilized in various fields such as web service backends, automation, and tool development. In this lecture, 45 things that beginners should know first when learning NodeJs are easily explained in order. Learning proceeds in a slide-based lecture format, and understanding is deepened by checking actual code execution results at each stage. Because it's structured to connect 'knowledge' and 'operation', you can naturally gain "aha!" moments of realization even without direct coding. If you grasp the overall picture of NodeJs at the beginning, subsequent programming learning becomes much easier.
