JavaScript Language Intensive Guide 🔥
I wanted to create a course that you don't need to take any other courses after taking it once. Many people feel like something is lacking when they jump into practice after taking a basic course as a beginner, right? In order to relieve you of the trouble of searching for advanced courses and content to quench your thirst, I planned and completed a course that delves into everything from 🍼 the basics for beginners to 🍺 advanced concepts and applications for practitioners, after a long period of preparation.
This course is a deep dive into the JavaScript language, and the application of web development is covered only in the last section. Please check the curriculum before taking the course.

Frequently Asked Questions
Check it out 💬
Q. What can I do if I learn JavaScript?
A. The uses of JavaScript today are endless. As a front-end developer, you can not only create websites, but also build Node.js-based servers. You can also create mobile apps or desktop programs, and you can use it for machine learning.
Q. I'm new to programming. Can I still take the class?
A. We planned and produced the lecture so that even those who are new to coding can follow along. We use easy terms so that even non-majors can understand without difficulty, and we explain the operating principles of the code in detail for those who have no programming experience. Since we utilize the browser console, you can take the lecture without a complicated installation process, and you can use the lecture page as a supplementary teaching material to follow the practice calmly. However, depending on the student, the progress may feel very fast , so if this is your first time taking Yalco's lecture , be sure to check out the free part in advance.
Q. I am already working with JavaScript. How helpful will this course be?
A. You can develop with just a 'moderate' knowledge of JavaScript, but if you have not studied it 'properly' and deeply, there is a limit to how much you can put the characteristics and strengths of this language into practice. If you take this course that delves into JavaScript, you will learn how to use JavaScript 'like JavaScript', and you will also learn how to analyze the functions you have used and utilize them more effectively. You will also be able to break free from the vagueness of what you know and don't know about JavaScript, and gain the confidence that you can do anything with this language.
Q. Will taking this course help me learn web development?
A. This course is designed to delve deeply into the grammar, theoretical knowledge, and advanced usage of the language itself called JavaScript. In the last section of the 16, you will learn about DOM and practice using it on websites in conjunction with HTML and CSS, but it mainly covers the core parts and analyzes them in depth from the perspective of JavaScript. If there is an opportunity, I will create a separate web development course that will fully practice front-end development.
Q. Is knowledge of HTML and CSS necessary or helpful?
A. (Linked to the question above) Since the part about using JavaScript on web pages only appears in the last section, you can take the lecture without any knowledge of HTML and CSS in the previous 15 sections. If you have basic knowledge, you can take Section 16 without much difficulty.
Q. The lectures are fast paced, so won’t they be difficult?
A. The video progresses quickly, but each lecture has a linked lecture page so that you can easily review and practice the video content. You will be able to learn in a way that maximizes your time efficiency by utilizing examples throughout the page and the browser console!

100% enrolledI really enjoyed learning JavaScript by studying and analyzing it using the browser console. I only knew a little bit about JS and used React and Node, but while taking this lecture, I realized a lot of things like, "Oh, this is how it works." Thanks to Yalko's easy explanations, I was able to learn advanced concepts easily. I think this will be a really fun lecture for those who want to study JS properly, as the title suggests. I especially recommend it to those who use JS in the field.

95% enrolledI've never written a lecture review before, but this is really...ㅋㅋㅋㅋㅋㅋㅋㅋㅋ It's amazing.. ㅎ.. I'm a non-major, but I'm really glad I started learning JavaScript through this lecture. I think it will be very helpful when I study other languages later. I was impressed by the way you handled memory addresses. . When I briefly studied C++ in the past, I was so confused about heap and stack in the memory section, but now I'm finally getting it sorted out. . It's so fun ㅋㅋㅋㅋㅋㅋㅋ Actually, I was a little worried because of the nickname, "Thin Coding Dictionary," but I paid the course thinking that I could finish it quickly because the content was light, but it was a huge surprise. ㅋㅋㅋㅋ It's a choice I don't regret. I think this is a lecture that only someone who has a deep understanding of the field can take. I realized that the basic grammar I've studied so far was very light. What lecture are you preparing next? I'm really looking forward to it..
- yalcoInstructor
I'm really happy to help you ㅠㅠ I feel like my hard work paid off!! The next lecture is about Java, which is widely used in Korea. I will complete it with even better content and present it to you. Thank you!!

70% enrolledWhen the class first started, I saw it for a few days and couldn't see it because of work, but I'm watching it again these days! Before, I had vaguely seen the contents in the book, so I didn't understand them well, but this lecture explains everything from the basics to advanced concepts really well and easily. I think that no matter what framework you use, you should have a solid foundation in the basics of JS, so this is a great lecture for solidifying the basics! I think I'll have to look it up and take it repeatedly if I get confused even after completing the class. Thank you~!

56% enrolledI'll leave a review after listening to up to the 9th lecture. This lecture is not a programming language lecture for beginners in programming, but rather a lecture for those who have completed at least the introductory level of other languages. Rather than slowly showing the taste of programming, it feels like delving into the JavaScript language itself. Those who find the lecture difficult should not try to memorize it too much, but rather fill up your 'coding skills' by solving simple problems or developing projects, and then come back. (Of course, those who understood the free lecture part should not be afraid and pay.) I had some experience with Java, so it wasn't difficult for me to understand, and I was able to learn by comparing the differences between Java and JavaScript, but if I had no development experience at all, most of the content would have been difficult to understand. And when the instructor looks at the code, he uses a lot of demonstrative pronouns like 'this', 'that', 'this function produces this result'. Unless the student is following the flow of the lecture perfectly and is concentrating on the instructor's mouse cursor movements, it is difficult to understand what 'this' means, so I think it would be better to intentionally avoid using demonstrative pronouns for better understanding of the lecture. ex) When I ran the toString function like this, this is the result. - X ex) When I ran the toString function with 2 as the argument, the string 0b11 came out. - O This review may sound like a harsh review, but I am listening with great satisfaction. Thanks to the lecture flow that quickly checks the example code and the result value and analyzes the result, It contains a lot of information in a short amount without being too long, And there may be explanations that are difficult for beginners to understand, but that does not mean that the explanations are unfriendly. If someone with some programming experience wants to know what kind of language JavaScript is, I think it is a very good decision to purchase this well-compressed and well-prepared lecture for the regular price of 50,000 won. *There was a pronunciation story, but I have never felt that the pronunciation was strange. I watch both Yalko's YouTube and Infleun lectures well. I love you.

[Additional response on 11/1/2023] In response to your comments, I have re-edited the entire lecture. I have slowed down the perceived speed by giving some leeway to parts such as screen transitions that were too fast, and added markers to make it easier to find the parts that are being talked about in the video. Please understand that it took a very long time. If you watch the videos again now, you will be able to take the class much better than before. Thank you for giving me your valuable feedback and helping me improve the lecture. Thank you for your good feedback, I have improved the lecture overall. Thank you again!! - - - - - Thank you so much for the detailed and thoughtful lecture review!! Thanks to you, I was able to confirm things I hadn't thought of, and I was able to think more about which parts I should improve more specifically and how I can be more considerate of beginners. I will try to reflect the parts you mentioned as much as possible in the next lecture to create better content. I am so glad and happy that the lecture was helpful to Park Jeong-sik. Thank you again for taking the class!

100% enrolledAs I was aiming for the 'backend', I reflected on the past days when the 'front' was simply focused on implementing functions. After going through the basics to advanced content, I realized that it was such a fun language. I think I need to go back and study it repeatedly (because I want to learn it properly and enjoyably) and I think I need to create prettier codes! It was a great lecture. Thank you.
