What is Kotlin ?

Kotlin is a modern language designed to work with Java and improve upon it. It’s used mainly for Android development, as well as other applications.

Background

Kotlin was developed by JetBrains in 2011 and has quickly become popular for Android app development. It’s now officially supported by Google as an alternative to Java for Android.

Main Concepts

Interoperability with Java

Kotlin works well with Java code, so you can use both in the same project.

Null Safety

Kotlin helps prevent errors by making you handle empty (null) values more safely.

Concise Syntax

Kotlin’s code is shorter and easier to read compared to Java, making development quicker.

Why Learn Kotlin?

If you want to develop Android apps, Kotlin is a top choice, as it’s officially supported by Google and often preferred for new projects.
