Simple Studying Curve
Kotlin goals to be an enhancement to Java, reasonably than a whole rewrite, so lots of the expertise you’ve got acquired and honed all through your Java profession ought to nonetheless be relevant to your Kotlin initiatives.
Mix the Better of Purposeful and Procedural Programming
Why select between practical and procedural? Kotlin brings you the most effective of each worlds by combining ideas from each procedural and practical programming.
First-Class Android Studio Assist
Android Studio makes configuring Kotlin in your mission as simple as opening a number of menus.Â
Extra Concise Code
For those who examine a Java class and a Kotlin class that produce the identical outcomes, the one written in Kotlin will sometimes be a lot shorter. And as each developer is aware of, much less code means much less bugs!
