Kotlin is a language for Android phones.
Kotlin is a modern, cross-platform, open-source, statically typed programming language. This versatile language was developed by JetBrains for modern multi-platform applications.
Nowadays, Kotlin is widely used for Android development because it is safe, concise, and fun to read and write. This blog will guide beginners to get started with Kotlin.
In this article, we’re talking about the books that give the most valuable to people learning their first programming language.
Why Learn Kotlin
Here are a few reasons why programmers and developers should learn Kotlin:
Easy to learn: Kotlin is very easy to learn and its syntax is very much similar to Java so you can remember it very easily.
Performance: Kotlin gives better performance and has a small runtime.
Popular: Kotlin has become very popular due to Google’s influence.
Concise: Kotlin keeps things brief and concise. It is more concise than Java and reduces codebase significantly when compared to the same code written in Java
Interoperable: Kaitlin is interoperable and we can use existing JVM libs and frameworks.
Safe: Kaitlin is safe and is impossible to get a NullPointerException
