The Essence of NodeJs Programming: 45 Things Complete Beginners Need to Know

This course is an introductory course on NodeJs that even beginners to programming can take with confidence. NodeJs is a technology that allows JavaScript, which was originally only executed in web browsers, to be used on PCs and servers. It is now being used in various fields such as web service backends, automation, and tool development, and is loved by many developers because of its advantages of being able to run quickly and lightly.

This lecture explains 45 things that beginners should know first when learning NodeJs in an easy and sequential manner. With slides that visually show how each concept works, you can check the actual code execution results at each step, so that theory and practice are naturally connected. It is structured so that you can intuitively understand the structure and flow of the code without having to code directly, so that you can have an “Aha!” realization.

From basic concepts to actual operations, you will experience the core principles of NodeJs beyond simple grammar memorization. For example, you will naturally understand why JavaScript is strong in asynchronous processing despite being single-threaded, and how NodeJs utilizes this. In the lecture, we will explain these concepts at a beginner's level, and also touch on structures that are frequently used in practice.

Also, I have included answers to questions that those who are new to NodeJs may wonder about, such as “Why learn NodeJs?” and “How is it different from other languages?” After finishing the lecture, you will not only gain simple knowledge, but also a sense of why the technology works the way it does. This will be a solid foundation for learning frameworks or server development in the future.

This course is designed to cover all the important concepts without missing anything while keeping the overall difficulty low, and to allow for natural review through repetition and organization. It is especially suitable for those who want to develop their ability to study on their own. It also points out areas where beginners often make mistakes or points that can be confusing, so it is also recommended for those who have had the experience of 'getting stuck while studying on their own'.

If you understand the overall picture of NodeJs at the beginning, it will be much easier to learn programming later. This course will give you a solid starting point to take that first step. Get started right now. We will be with you on your first step.
