This was a valuable lecture that helped me get a sense of optimization. However, could you possibly show the code a bit larger next time...? Even in full screen, it appeared small, so it was a bit hard on the eyes to follow along with the code on just one monitor 😭😭 Other than that, I'm completely satisfied. Thank you!!

This is a really great course for organizing the fundamentals~

I understand everything so clearly.. I can grow into a confident senior developer too!! I'll keep pushing forward!!

I really enjoyed it!

I'm a front-end developer just taking my first steps with React. I've learned so much knowledge. Even though it doesn't immediately click right now, it was very helpful to clearly understand what direction I should aim for in the future.

I listened well!

I usually just followed basic settings or company configurations, but this was a lecture where I could learn about the module system in detail!

This was a lecture that helped me understand why we need to know about build systems. At the end, you introduced follow-up lectures, and I'm curious about all of them, so I hope the lectures come out soon. Thank you for the great lecture!

It was great that you explained it in an easy-to-understand way.

I'm currently working on creating a wrapping library for personal use purposes. I was stuck right from the bundler configuration and felt overwhelmed, but I received a lot of help through the lecture. Thank you :)
