I'm enjoying this so much. I've been using JavaScript without this kind of deep understanding, but it's so interesting how you explain each technology by covering the situation before it was introduced and the reasons why it was adopted. I'm even doing Google searches and asking GPT questions while listening. I'd like to purchase and listen to your other courses too.

I enjoyed it so much! I'm curious if you have any intention of creating a React course as well. After listening to all the CS courses and then the JS course, I feel like I understand a lot more by connecting them, so I'd love to study React too!

It was great to be able to comprehensively review and quickly check JavaScript overall. The learning materials also included diagrams, which made it easy to organize the content in my head into writing or speech.

What you will gain after the course

Understanding Core JavaScript Concepts
The ability to explain verbally in technical interviews
Practical workbook PDF that prepares you for follow-up questions

🥲 Have you ever had this experience in an interview?

1. Confusing concepts when answering

❓InterviewerWhat are the characteristics of object-oriented programming?
💬 Candidate The SOLID principles. First, S is..(omitted)...
This is a situation where the characteristics of object-oriented programming (abstraction, encapsulation, inheritance, polymorphism) and
object-oriented design principles (SOLID) are confused.
This can give the impression that the foundational framework of basic concepts is not established.

2. Knowing only What, but unable to explain How / Why

❓Interviewer What are the characteristics of TCP?
💬 Candidate It's a protocol that guarantees reliability.
❓ Interviewer What mechanisms guarantee reliability?
💬 Candidate Uh... well... it makes transmission safe... like...
You only know the superficial definition and are not prepared to explain the underlying principles.
If 3-way handshake, sequence numbers, ACK, retransmission, flow control, and congestion control
are not connected as a single flow, you will inevitably get stuck on follow-up questions.

3. Getting stuck on basic questions

❓Interviewer What is HTTP?
💬 Candidate Um... it's for sending and receiving data on the web... something like that...?
It's a very familiar concept, but when you actually try to explain it in one sentence, the words don't come out.
This isn't a lack of knowledge, but rather a lack of experience organizing and articulating it.

Just knowing is not enough. It only becomes true skill when you can articulate it.

1⃣ CS Notes organized specifically for interview preparation

We compiled essential concepts and principles you must review before interviews into lecture materials.
While building your fundamentals, it's structured so you can review it again right before your interview.
Not just a simple summary, but with diagrams and easy explanations that even non-majors can fully understand.

Computer Architecture Lecture Material Example

2⃣ Appendix | Interview Practice Materials Provided

In interviews, the ability to explain clearly is far more important than simply knowing something.
However, organizing and practicing on your own is not easy and can be a tedious task.
At the end of the lecture materials, we've included "answering in one or two sentences" training to reduce the effort of organizing.

Database Course Appendix Example

3⃣ Prepare for follow-up questions with our Technical Interview Practice Workbook PDFincluded

"Will this course alone really be enough for speaking practice?"
After much consideration,
I created a Technical Interview Practice Workbook.
I designed it so you can practice speaking as if in a real interview even on your own.
You can find detailed information about the workbook structure and how to use it in the workbook introduction video at the beginning of the course.

Operating System Workbook Example

4⃣ A course that keeps growing with a one-time purchase

This course is provided with an unlimited enrollment period.
The content will continue to expand with new explanations, additional examples, and more.
Even if the price increases as content is added, students who have already purchased
can access all content at no additional cost.
It's a CS fundamentals book you can keep coming back to whenever you need it.

1⃣ Download the materials and learn the core concepts while watching the lectures.
2⃣ Take notes on important parts to create your own CS interview notebook.
3⃣ Save it on your phone and review briefly whenever you have time.

If you have an interview coming up,
and don't have much time → Use the appendix [Interview Practice] in the course materials to quickly sharpen your interview skills.
If you have time → Complete your speaking practice like a real interview with the Technical Interview Practice Workbook..

⭐️⭐️⭐️⭐️⭐️

1. A lecture that shows how much the author has thought and considered from the student's perspective (seems to consider the learner's flow of understanding)
2. Easy to understand with diverse visual materials and examples
3. When learning knowledge, it mentions and reminds you of previously learned content, connecting the knowledge. Knowledge connects and the big picture emerges.
4. The depth of knowledge is not shallow. I'm taking OS right after Computer Architecture, and the synergy is great.
5. Scratches the itch of "why" & "why is it used" curiosities.
ps. Sorry to the author, but.. this is a lecture I want to keep to myself.

-'Operating Systems' Course Review

⭐️⭐️⭐️⭐️⭐️

Despite the short lecture duration, I really appreciate how you clearly explain only the important parts. Since it was somewhat theory-focused, I didn't expect SQL queries to be covered, but it was great that you showed examples one by one while teaching basic syntax and how to write queries. After that, the coverage of joins, normalization, transactions, indexes and data optimization, and security was excellent. I haven't tried other paid courses yet, but the last lecture appendix titled "Interview Practice" showed actual questions and answers, which was great for self-study and practice. The lecture duration isn't too long if you focus, so I think I'll go through it multiple times. Thank you

-'Database' Course Review

🖐 Hello! Let me introduce myself! 🙇

As a non-CS major, when I first prepared for a developer job, I only focused on algorithms and coding tests.
I gained some confidence and passed most coding tests, but I kept failing at the next hurdle—technical interviews. What was the problem? It was the lack of CS (Computer Science) knowledge.

I understand the thirst for fundamentals (CS knowledge, programming languages, etc.) better than anyone. I dove into countless materials through self-study and built up my own know-how, and now I'm working as a 🧑🏻‍💻 Kakao developer.

Since I was young, I've been more confident than anyone in combining and restructuring various materials to create 'my own consolidated notes'. This course is that secret notebook containing all that know-how and passion.

Scope and Execution Context
- Scope, Lexical Environment, Execution Context, Hoisting, TDZ, this keyword, Explicit Binding, JS Runtime
Closures
- The concept and operating principles of closures, advantages and disadvantages from data encapsulation and memory management perspectives
JavaScript Operating Principles
- Single-threaded structure, synchronous vs asynchronous processing flow, how the event loop works (call stack, task queue)
Asynchronous Programming
- Callback functions and callback hell, Promise state changes and chaining, async/await syntax and error handling
Prototypes and Inheritance
- Object creation methods and constructor functions,
  The concept of prototypes and their connection structure,
  Various Prototype Inheritance Methods
Working with Arrays and Objects
- Array methods like map, filter, reduce, object destructuring and spread operator
JavaScript Module System
- ES module system structure, differences between import/export, dynamic import and code splitting
Browser and JavaScript
- JavaScript execution preparation process, script loading strategies, DOM and events, event propagation
[Appendix] Interview Practice
- Review key concepts once more in Q&A format

Recommended for
these people

Who is this course right for?

A non-CS major who feels lost because this is their first time studying CS
A computer science major who needs to organize CS concepts before a technical interview
A job seeker preparing for a career change who has limited time before a technical interview

Course Introduction

I am creating the
CS Speaking series to help you articulate CS concepts during interviews.

Teaching Philosophy

I started my development career as a non-CS major and went through a lot of trial and error while personally organizing everything from CS fundamentals to technical interviews. Based on the learning methods and conceptual organization know-how accumulated through that process, I create content that makes core concepts encountered in practice and interviews easy to understand through illustrations.

NATS: Ultra-low Latency and Messaging Distributed System Used by Naver Interviewers

Hong

When you're doing backend development, at some point you face this dilemma. As services grow and traffic increases, there comes a moment when simple REST communication and CRUD structures feel limiting. I experienced the same problem in real-world work and went through many trials and errors between performance and structural complexity. The solution I chose in that process was NATS. Its simple configuration based on a single binary, ultra-low latency performance in microseconds, and the fact that it provides just the right amount of essential features for real work—from Pub/Sub to Queue Groups and JetStream—made it a very practical choice in actual service environments. This course is not about listing NATS features. Based on the problems I faced in real work, I explain with code and flow diagrams which situations led me to choose NATS, why, and how I designed the architecture. This is a course designed to help everyone—from those new to messaging systems, to backend developers preparing for jobs, to senior developers contemplating better architectures—understand distributed systems and grow to the next level.
