[Renewal] ZeroCho's Introduction to JavaScript: Coding Self-Study

Learn Vue.js and Vuex and Vue Router, which are used with Vue, by creating 8 simple web games.

Learn React through web games. Get familiar with Classes and Hooks, and learn additional things like Context API, React Router, Webpack, and Babel.

With the arrival of the AI era, the skills required of developers are becoming increasingly complex. You might have thought, "I just need to be good at frontend," but when you try to create your own service or integrate AI features, you eventually hit a massive wall called the backend. However, as you try to start backend development, are you overwhelmed by how much there is to learn—from database design and authentication (Auth) to storage management and complex infrastructure setup? Now, you can lay down that heavy burden. In this course, we use Supabase, which solves all these backend functions at once. We will guide you through the fastest shortcut to becoming a full-stack developer who can "instantly" complete a backend without complex server knowledge and bring ideas to life immediately.

You will learn about what a node is, the latest JavaScript grammar, the node API, npm, the module system, databases, testing, and more. You will create a project using five practical examples. You will also deploy a service to the cloud and convert a node project to TypeScript.

Learn NestJS, often called the Spring of Node.js, and experience the convenience of Dependency Injection. Learn everything from API development and comparisons with Express to deployment and testing.

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

This is the first lecture of the JavaScript Bible course consisting of 4 lectures. It is faithful to the basics. It focuses on understanding the fundamentals of JavaScript. It covers more than 95% of the JavaScript specification.

This lecture examines the overall flow of core concepts that run through all of JavaScript up to ES6.

Rather than simply following a specific site, you will learn the scroll interaction know-how and key elements shared by knowledge sharers from the ground up, and learn and create various techniques and motions of UI scroll interactions widely used by domestic companies such as Apple.

I've included everything needed for those working with Vue.js in production. A learning note CRUD application implemented with actual backend APIs. Be sure to check out the messages about setting up a productive project environment and how to collaborate with backend developers :)

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

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.

Why does JavaScript use Classes? How was object-oriented programming implemented before their advent? Let's take a brief journey to find answers to questions you might ponder while studying JavaScript.

This is a JavaScript course designed to help you become a top-tier web developer through in-depth lessons. By completing the course, you will gain a deep understanding of the essence of JavaScript, allowing you to become an expert in React and Next.js, which you will learn next.

No matter how much you study React, Next.js, or Vue, if the code feels abstract and the structure isn't clearly understood, the root cause might be a lack of understanding of DOM. DOM is the foundation of all frontend frameworks and the entity that connects the structure and behavior of web pages. This lecture goes beyond simple selectors or manipulation methods, teaching step-by-step from the very beginning how HTML transforms into DOM objects and how to select, traverse, and manipulate this structure. It is the Part 1 introductory lecture of 'Complete DOM Mastery'. HTML tags are just structure, and JavaScript is just behavior, but DOM is the core that connects the two. If you clearly understand this connection, you'll be able to precisely grasp the true structure and flow within any framework you use.

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.

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.

🔥 Building a customized platform for learning Chinese characters! Utilize Google Gemini AI and Firestore to implement your own Chinese character vocabulary list, stroke order animations, and even handwriting recognition!

jQuery, the JavaScript library used by over 75% of websites worldwide! This course is designed to help you build a solid foundation by understanding the principles rather than just flashy effects. Learn everything from jQuery basics to advanced applications to complete your own portfolio or apply it directly in the field.

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.)

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.

The days of feeling relieved by black-box code spat out by AI are over. By piercing through the physical limitations of computers and the inner workings of the Node.js core engine, we provide you with the engineering control to remain unshakable in the face of any traffic surge.

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 :)

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

"2026 UIUX Designer | Coding Designer Agency Pass Portfolio Reveal" This is a practical lecture on creating a UIUX web portfolio that catches the interviewer's eye. The curriculum is designed not just for simple portfolio creation, but to enhance your competitiveness as a UIUX designer with differentiated results utilizing interactions.

We will write server code using the JavaScript-based web framework Express.js to understand basic usage and server operation principles. We will also study that frontend essentially requires a server, and enhance our understanding by learning about the processes behind various techniques such as static serving and dynamic rendering.
