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.

Let's use React and TypeScript together by adding TypeScript to a web game made with React and React Router, Redux, and MobX.

In this course, you will learn about TypeScript.

A current startup CTO will share vibe coding knowledge gained through actual services and various outsourcing projects.

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.

Coding No. 1 YouTuber Jo Coding's practical compression! Easy and fun web full-stack development lecture

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!

This is a process of creating your own backend API server, using Node-based Strapi v4, without any additional coding, with just a few clicks, and deploying it to AWS EC2. Almost the same can be applied to Strapi v5. Please refer to the lecture A/S as well~

We create a project site to create and distribute a psychological test site using only HTML/JS/CSS.

🔥 From course registration to video uploads, this is a hands-on full-stack course that implements knowledge creator features just like the real thing. Using Next.js 15 and NestJS, you'll build course creation, curriculum composition, thumbnail and video uploads, and detailed description writing following the actual Inflearn workflow, gaining near-professional experience with Prisma modeling, JWT authentication, S3 + CloudFront uploads, Swagger API design, and more.

Upon completing and applying these lectures, you can create your own sites and apps. This introductory VibeCoding lecture uses Cursor AI to help you naturally learn coding flow by creating a Web site group chat for your family. Without an App developer account or MacBook, anyone can easily follow along in a Windows environment, even without dev knowledge, and learn to deploy it as a real website.

"Why did the AI write this code?" or "Why can't it remember what I just said?" The frustration you encounter when using AI tools like Claude Code stems from not knowing how the tool actually works. This course flings open that black box. Over 25 lessons, we will build our own Coding Agent from scratch that functions exactly like real-world professional tools—giving the LLM 'eyes' to see files (Read), 'hands' to fix code (Edit), and 'feet' to execute commands (Bash). This isn't just about learning how to use a library. You will gain hands-on experience by implementing code to understand how AI perceives project structures, why it loses its memory during long conversations, and how to solve those issues technically (Sliding Window, Summary). Through this process, you will evolve from being a mere 'user' of AI tools to an 'AI provider' who understands the underlying principles and can customize and evaluate tools to fit your specific needs.

This course will help you develop mobile apps that can be serviced on Android and iOS using web development.

Full 40-hour Spring-based full-stack web development course, completely free.

With this one course, you can learn the basics of popular Javascript frameworks and Typescript.

A three-in-one class where you can create web games and learn front-end web development skills! This class has been created to teach you how to create games using JavaScript, CSS, and HTML with your own ideas!

Through this lecture, students can create a web service similar to Instagram using HTML, CSS, and JS. (Only the front-end is implemented! The back-end server construction will be filmed in a later lecture.)

While LLMs are currently transforming the development environment, what truly matters is not just "writing code on your behalf" but integrating them as features into a service. This course provides a step-by-step guide to implementing a lightweight yet polished Tarot reading service using Next.js and the OpenAI API. In the first stage, we will build an MVP that works without a backend, connecting the user input flow (questions/threads/card selection) to result generation. In subsequent stages, we will expand the functionality by building a backend, implementing general login and OAuth, adding community features, and creating a reading dashboard. Finally, we will conclude by deploying to AWS and integrating Google AdSense to complete a service ready for actual operation. Additionally, we will cover understanding pricing structures and cost optimization strategies to ensure that LLM API usage costs do not become a burden.

It took me a whole year to realize this.

This is a practical project course on running Whisper locally and quickly developing an AI speech recognition app using FastAPI and Next.js. You'll implement real-time speech recognition and complete a project that can be used as a simple portfolio piece in a short amount of time.

Through this course, you will learn not only concepts such as React and Node, but also how to practically create a website.
