A sophisticated yet still modern programming language, Kotlin is aimed at making developers happy. Code can be reused across multiple platforms and is very expressive, safe, and interoperable, as it enables reusing code between Java and other languages.
Kotlin Features :
- Multiplatform programming
One of Kotlin’s most important features is its support for multiplatform programming. While maintaining the flexibility and benefits of native programming, native programming reduces the amount of time spent writing and maintaining the same code for different platforms.
- Kotlin Multiplatform Mobile
The Multiplatform Kotlin Mobile SDK for mobile development simplifies the creation of cross-platform applications. Platform-specific code can be included only when it is needed in iOS and Android apps using KMM. Creating a native UI, for instance, requires dealing with platform-specific APIs.
- Kotlin for server-side
Developed with Kotlin, server-side applications can be written in a concise, expressive manner that does not require recompilation or revision, and can be easily learned.
Expressiveness: Kotlin provides powerful and easy-to-use abstractions with its tools, including its type-safe builders and delegated properties.
Scalability: Kotlin’s coroutines enable developers to create server-side applications that scale to a large number of clients with modest hardware requirements.
Interoperability: Kotlin is fully compatible with all Java-based frameworks, so you can maintain your familiar technology stack while benefiting from a modern programming language.
In Kotlin, you can migrate large codebases from Java to Kotlin by steps, gradually. The older components of your system can remain in Java while the newer code is written in Kotlin.
Tooling: The Kotlin plugin for IntelliJ IDEA Ultimate offers framework-specific tooling (for example, Spring) in addition to great IDE support.
Learning Curve: For a Java developer, getting started with Kotlin is very easy. The Kotlin plugin includes an automated Java to Kotlin converter.
- Kotlin for Android
Kotlin has been the first language for Android mobile development since Google I/O in 2019.
Kotlin offers the following benefits when used for Android development:
- Less code combined with greater readability.
- Mature language and environment. Aside from its development as a language, Kotlin has developed into a whole ecosystem with robust tools ever since its creation in 2011. Many companies are actively using it for developing Android applications now that it is seamlessly integrated into Android Studio.
- Kotlin supports Android Jetpack and other libraries. Existing Android libraries can be enhanced with KTX extensions to add Kotlin language features, such as coroutines, extension functions, lambdas, and named parameters.
- Interoperability with Java. You don’t have to migrate all your code to Kotlin to use Kotlin with Java in your applications.
- Support for multiplatform development. As well as creating Android and iOS applications, Kotlin can be used to develop back-end and web applications. By sharing common code, these applications can benefit from sharing benefits.
- Code safety. Easier readability and less code lead to fewer errors. This code is made safe by the Kotlin compiler, which detects these remaining errors.
- Easy learning. Programmers who are familiar with Java will find Kotlin intuitive.
- Big community. The community of Kotlin, which is growing around the world, offers great support and contributions. On the Play Store, Kotlin is used by more than 60% of the top 1000 apps, according to Google.
- Kotlin Native
The Kotlin/Native technology allows Kotlin code to be compiled into native binaries, which can be run without a virtual machine. A native implementation of the Kotlin standard library built on top of the LLVM backend. Kotlin/Native is primarily designed for platforms without virtual machines, such as embedded devices or iOS. Developers can use it when they need to create self-contained programs without requiring additional runtimes or virtual machines.
- Kotlin for data science
Working with data can be made easy with Kotlin, whether you’re building pipelines or producing machine learning models:
- Kotlin is a concise, readable, and easy-to-learn programming language.
- With static typing and null safety, you can write reliable, maintainable code that is easy to troubleshoot.
- Since Kotlin runs on the JVM, it offers great performance and the ability to leverage an entire ecosystem of Java libraries.
