Hello
I have come here to understand the usage of slack for Kotlin. I am a newbie in Kotlin and I am completing the codelab on android app. My current queries are on why one solution is better than the other in terms of coding. Please do let me know if it is alright to ask in getting-started channel. I do not intend to crate noise hence posted here.
