If you know good code,
You can make good software.
Even if they create the same function, the code of a junior developer who has just learned JavaScript syntax and an experienced senior developer are quite different. Of course, the result is the same. The reason the latter's code is recognized is because of its well-organized design and extensibility to respond to changes. This lecture will teach you how to create such good code.
First, let's look at the characteristics of JavaScript and why TDD (Test Driven Development) is necessary. We'll proceed with code examples commonly used in practice. We'll diagnose problems in the code together and go through the process of improving it step by step. Then, we'll look at the theory of TDD and design patterns. By applying this to refactoring, you can eventually create good quality code.
Each lecture is less than 10 minutes long, so you can start over at any time. The branches prepared in the middle of the video are a small consideration for those who were unable to practice. However, I strongly recommend that you participate in the class by coding step by step.
“I know JavaScript grammar, but I don’t know how to develop.”
“I’ve heard of TDD, but I’m curious about how to do it.”
“I would like to see only minor changes to the code, even if the requirements change.”

A working developer who loves learning and organizing web technologies.
I run a technology blog about web technologies and my thoughts as a developer.
We also share the skills we have learned and the know-how we have learned in practice in the form of presentations or lectures.
I work as a front-end developer at Elegant Brothers.
I also wrote content related to React technology.
It's neat
You explained TDD very easily. I enjoyed watching it because you explained the concept of TDD very easily. Your source code style seems similar to React or Vue. I have a question. In a project that cannot use ES6 yet, you will need to convert it to ES5 and distribute it. Can you guarantee that the code tested in ES6 will pass the test even after converting it to ES5? Thank you for the great lecture. I will watch other lectures as well!
Thanks to Kim Jeong-hwan's lecture, I was able to get a feel for what it means to write good code. I am a non-major and a student who has only been learning programming for a few months. I only heard people talk about good code and clean code, but I didn't really get a feel for what they were. Then, my mentor always recommended that I try coding with TDD. He said that it would help me make it a habit to track my work in very small units. So I looked for Kim Jeong-hwan's lecture. In addition to thinking in small units, I think I got a feel for what DRY code, which I had only heard about all the time, was like. Not only this lecture, but also the Node TDD development and the articles you wrote on your blog are really good. Thank you for providing such great lecture materials.
It's fun. It's simple, but it contains a lot of content. From TDD to things to watch out for when developing JavaScript. And even the object concept... The instructor seems to apply those things naturally, but I'm not at that level yet. I'm learning a lot.
There aren't many front-end TDD classes. I tend to listen to Kim Jeong-hwan's lectures as much as possible. When I became interested in test-driven development, I bought the lecture and listened to it all. I think it will be a helpful lecture for beginners because it explains things easily. It's a bit short, so it's hard to understand the in-depth content, but I think it's a good lecture to start with. Thank you for always giving great lectures.
