I was able to learn the basic concepts of module systems and build systems in great detail, and it's tremendously helpful to the extent that I can apply it directly to practical work.

Thank you for the in-depth lecture!!

In practice, there was this vague feeling of "this would probably work like this, and that would probably work like that." Before taking this course, I didn't know everything about bundlers and only knew the surface level. After taking this course, it was great to learn everything from the core structure to the detailed operating principles. Thank you so much for such a wonderful course!

It's a thousand times better than typical React or Next.js lectures~ and it's fun too. Above all, I doubt there's a lecture that explains the module system, one of the foundations of JS, more easily and deeply than this one. From the history and development process of module systems, from CJS, AMD, UMD to ESM, I was able to learn in detail why such methods emerged, including their implementation and specifications. The lecture style of deepening understanding by actually implementing it was also great. I'm very much looking forward to the next series :)

The JS module system, which I always found confusing while doing frontend development... seems to be getting sorted out as I listen to the lecture. Not only the concepts of CommonJS, AMD, ESM, UMD, but also the historical context of why such structures emerged has been explained, so a framework is being established in my mind. Especially, by showing how the module system works in modern tools like Webpack and Vite, by examining actual configuration files, I'm reflecting on myself who used to be at the mercy of tools. 😊😊 I will diligently listen to the remaining lectures and strive to grow significantly. Thank you for the great lecture :)
