The [Stunning Web UI Styling with Tailwind CSS] course covers the currently hottest framework, Tailwind CSS v3.4.1, in depth over 19 hours, ranging from theory to building a practical responsive website. A long course duration doesn't always guarantee quality. However, I am confident that this is a high-quality course that also happens to be comprehensive. In particular, it covers all Tailwind CSS theories in detail for 8 hours and 30 minutes, allowing those with a weak foundation in CSS to thoroughly learn the core concepts. This course is centered around Tailwind CSS styling as created by developers and publishers.

We will understand the concepts of classes and components in Bootstrap5, apply them, modify them, and create three projects through practice.

This lecture is a lecture on JavaScript from the [Web Development Full Stack Course] lecture series for training full-stack web developers. This lecture is based on the contents of the book <Vanilla JavaScript> written by the knowledge sharer.

Practical web UI development using AI and component-centric UI creation, An essential course for Designers + Developers!

"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.

Transform complex data flows into declarative ones with Lodash. Learn how to use Lodash in practice, going beyond map and filter to chaining and advanced utilities.

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.

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!

In the era of agents, true skill comes from 'control.' You will perfectly master the operating principles of agents by building the core architectures of Claude Code—Agent, Tool, MCP, Skill, and AgentTeam—from scratch.

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