Hello springbom! Thank you for your detailed review. 😊 I put a lot of thought into delivering content that maximizes the advantages of Kotlin while also being applicable in real-world situations. I selected and included only the most meaningful content based on studies with colleagues, practical application experience, and various references, so I'm really glad it was helpful! In particular, if you utilize the tips covered in the lecture and share the advantages of Kotlin with your team, I think the transition from Java to Kotlin will be much easier. I will continue to work hard to produce good content that is helpful in practice. Thank you! ✨​​​​​​​​​​​​​​​​
