[React / VanillaJS] Creating UI elements directly Part 2

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

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.

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!

This is a study video that follows the contents of the book "Modern JavaScript Deep Dive". It will be much easier if you study together!

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

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.

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.

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.

Let's start serious React web development by creating it following the Slack service! From sign-up, login, room creation, to real-time chat!

Let's create a Twitter-like SNS service with React & Next & Redux & Redux Saga & Express stack. Finally, we will deploy it to AWS after SEO.

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!

This course goes beyond simple DOM manipulation, deeply learning how to dynamically compose and react to web UIs within interactions with actual users. It's structured for you to learn by directly implementing common issues encountered in practice, from the essence of event systems, bubbling and capturing, event delegation, real-time UX feedback, to performance optimization using throttle & debounce. Based on an understanding of the DOM tree structure, you will develop the ability to flexibly connect event flow and state changes.

Web developers (especially React developers) can now truly easily launch apps. With Expo, you can launch both Android and iOS apps even faster. Let's become a developer who can quickly launch apps with Expo.

The ultimate full-stack course that teaches even beginners about web, server, mobile apps, and machine learning!! If you're not sure where to start with development, I highly recommend this course. It's all done with just Javascript!

This course is a full-stack level frontend project course that focuses on implementing Notion from start to finish using Vanilla JavaScript, going beyond simple UI cloning to deeply understand the internal operating principles. You'll implement all the core features of a real note-taking app using vanilla JS, including sidebar tree, nested document creation, auto-save, routing, trash, favorites, search modal, settings modal, theme switching, Export/Import, keyboard shortcuts, responsive layout, drag resize, and more. The goal is to solidly learn browser standard behaviors (event bubbling, DOM tree, local storage, Blob, FileReader, hash routing, etc.) that you must know before frameworks like React and Vue, so you can completely understand "why it works this way" and build the skills to debug effectively.

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

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

Springboot + React RestAPI Bulletin Board Creation: Learn Faster Than Anyone Develop a CRUD server with Springboot and create your own board with React!

The goal is to acquire basic knowledge of React Native for mobile app front-end development. This course is designed to enable non-experts to easily develop native mobile apps by utilizing languages/APIs with low entry barriers.

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

Master React rendering principles and optimization to apply them in real-world situations and prepare for interviews!

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.

How are you using TypeScript, the standard of Node.js? If you only add type annotations, it is not real TypeScript. I prepared everything because I don't know what you will like. Let's learn TypeScript A to Z :)

In this course, you will learn about TypeScript.

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.

Explore → Plan → Implement → Commit. Master the proven AI development workflow with Claude Code. Learn through 23 missions covering MCP, sub-agents, and prompt engineering, and complete 3 real-world projects.

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.
