Reading – Kotlin for Android Developeprs

Just read the Kotlin book after listening to the Fragmented podcast with JetBrain engineer which mentioned in the previous post (Watching – Mouseless driven development).

I heard of the language several times, but didn’t have chance to look at it. This time, I made up mind to investigate more.

The Getting Started with Kotlin in 2 minutes is a good introductory video for understanding its syntax and behaviors. Kotlin works on JVM and its concept and syntax are mainly coming from Java, but also good parts of Scala or Groovy is incorporated and making it modern language.

Scala has powerful extension of type-safety and functional-programming, but it’s a little too complex. Groovy has concise syntax and good productivity on small programs, but it’s a little too loose to cause dynamic exceptions like NullPointerException. Kotlin seems going between the two, and if the balance is good, it may be worthwhile to dig in deeper.
