Kotlin is a modern programming language that runs on the Java Virtual Machine (JVM) — and it’s now the official language for Android development.
Created by JetBrains and released in 2011, Kotlin was designed to fix some of Java’s pain points. It’s more concise, less prone to errors (like null pointer exceptions), and fully compatible with existing Java code. That means developers can mix Kotlin into old Java projects without breaking anything. It’s also expressive — you can do more with less code, and it reads closer to natural language.
Why do developers love Kotlin?
Because it feels fresh but familiar. If you’ve ever worked in Java, switching to Kotlin is like upgrading to a smarter keyboard — you type faster, make fewer mistakes, and still speak the same language. Since 2017, Google has officially recommended Kotlin for Android apps, and it’s also gaining traction in backend development and cross-platform frameworks like Kotlin Multiplatform.
