I think John Ahn's lectures are great. He provides a low lecture fee, even makes the textbook himself, and the contents are also informative. How can I take another React lecture when I can take a lecture like this, which is rich in content and affordable compared to other lectures?

1. Lecture materials - 5 points There are many attractive GIF materials, but it is unfortunate that the GIFs are not included in the PDF, and the pictures of the parts where the pages are divided are cut off when exporting from the diagram app. ㅠ It would be good if Infraon had standards or guidelines for documents. I have seen some instructors use Hangul files.. Still, the lecture materials are perfect quality, so I give them 5 points 2. Lecture delivery - 5 points This is the first time I have left a review saying that the voice is good. It is easy to listen to. React was difficult when I used to read books or study on my own, but I learned well thanks to the kind lectures that teach important things more, and do not just roughly draw them with a drawing program, but with proper diagrams or materials. While listening to this, I got 3 other lectures recommended by an acquaintance, but after comparing them, this seems to be the best for learning React and for beginners in the front-end. 3. Lecture structure - React~TDD is 5 points, 8th and later 4 points React and testing, distribution, and automation are explained very well, but TypeScript, Next.js, and Redux are not explained in detail, which is unfortunate! It's not that the lectures are lacking, but the latter part only covers the introduction. It would be good to have an intermediate course~ 4. Overall evaluation This is a perfect lecture. The price is relatively cheap compared to the quality.

This is a great lecture to lightly remind you of the basics you need to know when working on the front! I plan to watch this lecture again after each project to refresh my memory.

From React basic concepts to intermediate techniques
You can learn by creating your own app!
In this course, you will learn React skills from basic to intermediate level .
Even those who are new to React can acquire most of the knowledge they need for React with just this one lecture.
I made it so that you can learn the concepts and practice in one lecture, and acquire most of the knowledge necessary for React at once. I hope that learning React, which is considered essential to become a front-end developer, will be of great help in getting a job.
Helps with structural understanding
Diagram-centric
Easy and detailed explanation
Directly the source code
While writing
Natural repetition learning
Real world applications
Can be made
Practice-oriented lectures
Learn the basics of JavaScript
If you are a beginner developer
Anyone OK!
Because it is easier to understand visually through diagrams than just listening to an explanation. Also, I think that learning through diagrams like this and then writing source code naturally has a reviewing effect.
First, learn the necessary concepts, and then practice to solidify the concepts.
If you know the basics of JavaScript, you will have no difficulty taking this course.
Section 1) You will learn about the concepts of React.
Section 2-3) Learn and use basic React concepts while creating a To-Do app.
Section 4-5) Learn and use more advanced concepts of React while creating a Netflix app.
Section 6-7) Learn the basics of React testing and create a simple button app through practice.
Section 8) Learn about NextJS and Typescript and create a blog app using them.
Section 9) Learn about the new features and APIs in React 18, the new version of React.
Section 10) Learn about Redux, React's representative state management library.
Section 11) Learn how to run React with Docker.
Q. Is this a lecture that non-majors can also take?
A. Since the lectures are given in detail from the basics, even non-majors can take the course.
Q. Why should I learn React?
A. I think learning React will be very helpful for getting a job, as it is the most used library as a front-end developer.
Q. Is there anything I need to prepare before attending the lecture?
A. It would be good to know and listen to basic JavaScript concepts.
