Introduction to Frontend: Understanding JavaScript the Easiest Way

This is a TodoList tutorial taught in the simplest way by a third-year frontend developer.

🚀 This is a mini-project practical lecture suitable for those who have just finished studying JavaScript grammar. It will help you break through the gap between basic JavaScript grammar and frameworks such as React or Vue. ✨

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.

A full-stack series course aimed at beginners, based on real-world experience developing actual web services, with the goal of building web and app services to a level suitable for actual commercialization. As Part 2 of this series, this course thoroughly covers the latest HTML5, CSS3, and Vanilla JavaScript (Javascript) + ES6, including responsiveness and compatibility, among the many available frontend technologies.

You can learn React's state and hooks in a broad, deep, and detailed manner. It covers over 95% of the official React documentation. You can master React with this single course.

This course is not about "Let's build something amazing with the latest technology," but rather the most practical web development beginner course that makes you feel "You can build it yourself with just a little knowledge." We'll create the basic structure with HTML and JavaScript, exchange data using Node.js and SQLite, and complete a simple web page with Next.js. We minimize complex configurations and difficult theories, and focus on getting a hands-on feel for web development flow by writing code that actually works. This course centers on 'hands-on experience' rather than just 'learning.' If you've touched code even a little bit, anyone can follow along and feel the satisfaction of completion.

The Ultimate JavaScript Course! It covers execution context structures and mechanisms based on ES2025, the Event Loop, and multi-threading. It also explores the language culture embedded within JavaScript.

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

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

Fundamental JavaScript knowledge needed for frontend development. Essential knowledge that practitioners must know, explained easily and quickly. A basic course reflecting modern frontend development trends of 2024.

"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 full-stack hands-on course where you will implement a ChatGPT clone from scratch. From Spring Boot server to React frontend | Neo + Essential This is not just a course where you simply follow along with the code; it guides you through actual service deployment so you can build a high-quality AI chatbot service.

This course goes beyond simply using Express.js. You will rebuild its internal engine from start to finish, gaining hands-on experience with the real principles of how a server works. By directly creating each component of Express—such as routing, middleware, request–response objects, static file handling, and template rendering—you will grow as a server developer and truly understand how a framework operates at its core.

This course goes beyond just using Express.js—you'll implement its internal engine from scratch to truly understand how real servers work. You'll gain hands-on experience growing as a server developer by building all of Express's components from the ground up, including routers, middleware, request-response objects, static file handling, and template rendering.

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.

This course is a practical, hands-on guide for those who want to learn how to maximize development productivity in the AI era. Beyond simply learning how to use AI, we focus on how to utilize Claude Code in a real-world development environment and how to produce "proper results." Many developers use AI but still face issues such as: ❌ Inconsistent results ❌ Poor code quality ❌ Increasing project complexity To solve these problems, this course teaches you how to utilize AI as a "development partner" rather than just a tool through: ✔ Spec-based workflows ✔ Structured command systems ✔ Sub-agent and automation strategies Furthermore, you will gain the experience of completing and deploying a full application from start to finish by integrating with real-world services such as Firebase, Figma, GitHub, and Vercel.

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 have created this so that anyone can pass the 2023 version of the Web Design Function Exam Criteria. Let's learn the 5 types and pass quickly!
