[React Part 2] Advanced Topics and Hooks

From HTTP basics to data requests, real-time communication, security, and performance optimization, learn the network knowledge web developers must know.

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

I can understand pre-existing development environments. I can create a development environment from scratch.

You can learn intermediate Vuejs techniques (Vuex, Vue-Router, Http) through the process of implementing other web applications with your own hands. This is a lecture where you can also experience how to collaborate, as publishing results, API servers, and documentation are pre-configured.

Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

We will learn VueJS development by creating a shopping mall search page using pure JavaScript and a UI library called VueJS. You can learn the differences between each development and the differences between MVC and MVVM design patterns by developing with pure JavaScript and VueJS respectively.

In this course, you will learn NodeJS, which allows you to develop backends using the Javascript language, and develop API servers using NodeJS using the test-driven development (TDD) method. You will also understand the basic principles of ExpressJS, a representative web framework for NodeJS, and learn how to develop REST APIs used in mobile and web services.

I will help you gain the deep understanding and unique perspective needed in the AI era, from technical interviews to practical system design, by diving into the source code together. Grow from a developer who has simply "used" Next.js into an expert who "understands" why it is used that way.

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.

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.

Have you ever thought about building a 'real system' beyond simply rendering screens? The real problem many developers commonly face is something else entirely. It's the limitation of a 'fake full-stack'—where things look plausible on the surface, but data synchronization frequently tangles, speed is frustrating, and you lose track of where to even start when just a few features are added. This isn't a problem that can be solved by simply memorizing one more Next.js feature. This course will resolve that frustration from the roots. Encyclopedia-style classes that just list features are boring, aren't they? Instead, we have tightly integrated the fundamental principles of Computer Science (CS) with the advanced architecture of Next.js. We will directly transplant into your fingertips the enterprise-level design skills required to flexibly withstand millions of visitors and maintain perfect data consistency.

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

In this course, you will practice step-by-step using React and FastAPI to implement social features like real-time voting, comments, and likes, as well as integrating payment systems (KakaoPay, TossPay, etc.) for monetization.

This course is designed to learn the JavaScript programming language along with the latest ES6 grammar.

3D Globe Article Service with ThreeJS and SpringAI | Neo + Essential Create your own 3D globe article service using your personal chatbot and ThreeJS!

This course will help you learn JavaScript through theory and practice. It explains step by step so that even beginners can easily understand. Part 2 covers JavaScript functions and events, types of functions, and core libraries.

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 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.

A course where you understand core JavaScript concepts and train to explain them verbally for interviews.

It covers machine learning concepts within the JavaScript environment. It covers the patterns and code for implementing machine learning with JavaScript and TensorFlow.js.

A full course of hands-on Next.js! Complete a real-world project with the latest technologies such as GraphQL, Redis, RabbitMQ, Prisma, TailwindCSS, Docker Compose, Cypress, Prometheus, and Grafana, and experience both the App Router and Page Router.

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

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.

jQuery, a JavaScript library used by over 75% of websites worldwide! This course is structured to help you understand the principles and build a strong foundation rather than focusing on flashy effects. Learn jQuery from the basics to advanced applications to complete your own portfolio or use it immediately in the field.

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!

I have summarized how to create a profitable AdSense website. I have organized it so that even those without development experience can follow along, leaving only successful methods so that they can be replicated exactly.

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