The best course for quick and easy skimming.. It's really the best for quick skimming! This is a course where you can get a basic framework and feel like, 'Oh, this is the language!' However, you'll definitely feel that Kotlin is not just about what's introduced in the course. I think you'll need to supplement it with books or other courses! If you read the comments carefully, you'll see how kindly the instructor points out things that can be confusing.. It's good ㅠㅠ
