I started learning Kotlin without knowing Java, and it was great that you focused on the essential parts. However, there were concepts like scope functions that suddenly appeared in the practice sessions, and some explanations felt like they were continuing from Java, which left me a bit confused each time. I think these issues arose because you compressed everything into a short timeframe. Still, thank you for providing a high-quality lecture for free.

Hello! I’m Neo, an instructor on Inflearn. | Current Platform Engineer
My goal is to make development technologies that people would not normally encounter accessible to a wide range of learners.
Therefore, rather than simply listing theories, I aim to create a practice-oriented curriculum and provide hands-on courses that learners can follow without troubleshooting.
The content is designed with an approachable and friendly style so that even beginners can follow along without feeling overwhelmed, with a particular focus on lowering the barrier to entry to knowledge.
Sometimes, I also work on courses with like-minded people!

Thank you for taking the course! Since this is my first language course, I wanted to make it perfect from the start, but as I was creating it, there were dubbing issues in the middle and the quality didn't turn out as well as I expected, so I had a lot of doubts about whether I should upload this even though it's free...? But seeing so many people enjoying it really gives me strength! I'll finish up the additional courses I'm currently working on and do my best to update with more detailed content soon. Thank you!
