Let’s take a closer look at what a Kotlin developer is and how the need for Kotlin developers is growing.


What Is Kotlin?

Kotlin is a modern, compact, and cross-platform general-purpose programming language that works seamlessly with Java. Safety, interoperability, excellent tools support, and clarity are all priorities.

Why Kotlin For Android Development?

With Google’s official support for Kotlin, the answer to this question became clearer. Since Google I/O in 2019, Android development has shifted to Kotlin. This is because Kotlin is often thought to be superior to Java.

It’s expressive, type-safe, and null-safe at the same time. While Kotlin is not a replacement for Java, it integrates well with the language, making it simple for developers to use both Kotlin libraries and Java at the same time.

Developers can use as little or as much of the Kotlin language as they desire because it is 100 percent compatible with Java.

Key Advantages Of Kotlin:

  • Secure and concise code
  • Interoperability with Java
  • Easy debugging
  • Modern, faster, and safe
  • Compiler efficient
  • Easier to maintain
  • Boosts developer productivity
  • Supports multi-platform development
  • Less and clear code

Over 60% of professional Android developers use Kotlin to improve productivity, developer happiness, and performance.
