We sincerely thank everyone who has always shown love and support for JSCODE courses.

I hope you have a bountiful Chuseok holiday filled with warmth and joy, shared with your loved ones! 😊

First, thank you for your interest.

More than 100 people have taken the course within just 5 days of releasing the e-book,

I was very motivated seeing people leaving questions even on the year-end weekend.

I notice that the `` tags are empty - there is no Korean text between them to translate. Could you please provide the Korean text you'd like me to translate?

I have improved the readability of the e-book (PDF file) provided as course materials.

• Increased letter spacing

• Increased line spacing

• Modified the layout of text and images

I modified it focusing on readability to reduce eye strain when reading content on one screen.

I will continue to make gradual improvements whenever I notice any inconveniences. Thank you!

I will continue to make improvements, even if small, whenever I notice any inconveniences.

Thank you!
