[React / VanillaJS] Creating UI elements directly Part 1

The ES6+ Understanding Course takes an in-depth look at the differences from ES5, concepts, and operating principles of ES6 and the subsequent standard ECMAScript specification for Javascript based on theory.

From development to distribution! We will show you the arduous journey to complete a single service without filtering. You will be able to overcome the difficulties and difficulties by introducing a lot of new technologies!

Practice REST API and GraphQL while creating a simple SNS service based on React. We introduce how to easily and simply create a backend environment for frontend development.

This is a study video that follows the contents of the book "Effective TypeScript". It will be much easier if we study together!

By creating representative UI elements in React and pure JavaScript versions, you can experience various perspectives and methods using Web APIs and further improve your front-end development skills.

Let's learn together the official React documentation that has been renewed in 2023.

Master React now. Easiest course to grasp React's features & roles, comparing to pure JS!

We solve the fundamental problem of losing control amidst AI-generated fragmented code and the complex React ecosystem by opening the hood and engineeringly analyzing the internal workings of core React libraries such as Zustand, TanStack Query, React Hook Form, Zod, and the React Compiler. By moving beyond simple tool usage and mastering how to directly manipulate the performance and data flow of the React engine, you will build the solid 'enterprise architecture design muscle' necessary to respond immediately to any crisis.

We develop an avatar-based community app with React Native. You'll learn to build a comprehensive community app, covering post creation, comments/replies, likes, voting, avatar generation, etc.

This is a highly concentrated Typescript grammar lecture that will turn you into a Typescript grammar expert with just one lecture, even if you don't know anything about Typescript.

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.

In this course, you will learn about TypeScript.

This is a course where you will build a map service from scratch using the MERN stack (feat. TypeScript). Let's build it step-by-step while following the official API documentation.

In this course, you will learn how to create a chat application using React and Firebase.

"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.

This is a mission content for a frontend project. We provide a PRD planning document, Figma design, and API endpoints so you can practice the project by implementing a timer app called DevTime yourself. Make the knowledge you've learned so far completely your own by implementing a project at a level similar to an actual service 🚀

This is a practical course where you will directly create a timer app using React, Electron, and Zustand, and even deploy it to cross-platforms (Windows, macOS, Linux). Starting with familiar React web development, you can learn the entire flow of desktop app development, including global state management via Zustand and final GUI deployment!

You can gain the ability to implement a chat program in just one hour using Next.js + Cursor IDE.

"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.

Building your own emotional diary service with Spring AI + React It's time for our 4th project with Neo + Essential!

A Complete End-to-End Developer Journey — Build Lightning-Fast APIs, Modern Frontend Interfaces, Real Projects, Authentication Systems, Dashboards & Full Deployments Using FastAPI, React, and Vibe Coding Techniques.

This course is about TypeScript and React.

JavaScript, TypeScript Next is backend development! You will be able to develop REST API backends using NestJS, develop and deploy Socket IO.

I recommend this to those who want to learn how to easily create and distribute Android apps, Windows apps, and iOS apps. We will teach you the basics of TypeScript rather than JavaScript and Angular!

Throw away those simple services you can make with vibe coding in just 10 minutes! You can learn 'real' practical vibe coding. Let's create advanced services at the level of actual services according to planning and design with Cursor AI NCOP. No Code, Only Prompt
