New Dimension's Kotlin Course

*Warning: Outdated Content* This content was created in 2017. Since it is quite old, it may not be compatible with the latest versions, so please use it for reference only. This is a course on the Kotlin programming language. Google recently officially added Kotlin as an Android development language. However, there is currently a lack of translated books or materials for learning Kotlin in Korea. While kotlinlang.org has well-organized information about Kotlin, it is only available in English. Therefore, I have studied kotlinlang.org myself and summarized the content into videos. I have compiled these materials in hopes that they will be helpful to others studying Kotlin.

This was my first time taking a lecture on Kotlin, and it was very helpful. I look forward to more great lectures in the future! It was easy to understand because you compared it to Java and showed examples!

I am a beginner who has never tried Kotlin before. I was looking for tutorials on the internet and found Saechawon's lecture, which made it easier to understand. Thank you for the lecture!!

    I think you should learn how to speak before learning how to code.

    The lecture content itself doesn't seem bad. It's okay for beginners to learn because it explains things step by step based on references. However, there are a few things that bother me outside of the lecture content, so I'm leaving feedback. 1. Keeps blurring the end of your speech - You keep blurring your speech, and this seems to be a bit distracting. It would be better if you spoke more clearly and to the end. 2. Pronunciation - You kept pronouncing the word 'error' as '어', '오루', '오루', etc. I didn't pay attention to this at first, but after listening to it more, I started to notice it strangely, and basically, your pronunciation is not clear and sounds awkward. It would be better if you paid more attention to your pronunciation. 3. Sometimes you stutter or ramble - When you lecture, you stutter sometimes or repeat the same thing over and over again, so it feels like you're not prepared for how to conduct the lecture. I don't know how much you prepare and film the lectures, but there are times when I feel frustrated and skip over them. Since the content itself is a field that I don't know much about, I'm listening carefully to the parts where you explain based on references. However, as I said above, if you pay a little more attention to your speech and lecture progress, I think it will be a much higher quality lecture.

    It doesn't feel awkward, but it seems like a suitable lecture for someone who is just starting out with Kotlin. It was helpful. Thank you~
