Sneaking inside Kotlin features

EN JA(Simultaneous Interpretation) Cards － 2020/02/20 17:00-17:40
Kotlin
Kotlin has many language features even though none of them are supported by JVM or Android ART. This talk will go through all the language features and understand how they work internally for JVM or ART compatibility. For example: 1. Do all know, how features like default arguments and default methods (in interface) works? 2. Do all know, that switch statement can only work with integers? Then how when expression works with almost all data types? 3. Do all know, how inline classes works? 4. And many more features. Many developers in kotlin community uses all these APIs without knowing how they work. After this talk, they will have a good understanding of how these features work internally which obviously make them a better programmer.
