Why use Kotlin?

Contents

Kotlin is a cross-platform, statically-typed, open-source programming language that runs on the Java virtual machine (JVM). Developed by JetBrains, the project started in 2010, with the first official release in February 2016.

Code written using Kotlin works as well with Java as it does natively, meaning it’s interoperable. Kotlin uses aggressive inference to determine values and expressions.

Kotlin is concise, type-safe, and reliable. It has both object-oriented and functional constructs and is usable for any kind of development. That includes server-side, client-side web, Android, and iOS. It’s also supported by all major Java integrated development environments (IDEs), including IntelliJ IDEA, Android Studio, Eclipse, and NetBeans. Support like that helps increase developers’ productivity.

Additional Kotlin language features include clean and compact syntax and null safety. That translates to mobile apps that are easier and cheaper to maintain, and more efficient teams.

Kotlin for business software development

Being 100% compatible with the JVM, you can use Kotlin for server-side development. Write expressive yet concise code while maintaining full compatibility with Java.

Kotlin is compatible with all Java libraries and frameworks, the JVM, and can integrate with the Gradle and Maven build systems.

As well as using for back end web, you can use Kotlin code client-side, for desktop development, and native development. It also supports modern programming concepts like extension functions, higher-order functions, and lambdas.

What’s more, adopting Kotlin doesn't cost anything, except for learning and training. Switching to Kotlin is easy: install the plugin, add it to your build files, and click convert.

Advantages of Kotlin for Android development

In 2017, Google made Kotlin a first-class language for writing Android applications. That opened up opportunities for Android developers, helping them solve common headaches like runtime exceptions and source code verbosity. Applications such as Basecamp and Pinterest use Kotlin for Android.

It’s easy to get started with Kotlin, and you can write new modules in Kotlin and be sure they’ll work alongside Java code. That means you can gradually introduce it into existing projects. Furthermore, there’s preservation of skills and technology investments.

Kotlin is a concise and powerful language. It reduces the amount of boilerplate code required, enhancing productivity. There’s less room for error, meaning safer, more reliable code. There’s also built-in safety support.

The more you can enhance Android app stability by removing bugs and minimizing crashes, the better the user experience (UX) is.

Is Kotlin Better Than Java?

Kotlin has a lot of traction in Android development and compiles to almost every platform. It’s more concise and expressive than Java and switching is easy. There’s built-in null safety support, but Kotlin does come with a steep learning curve and has a smaller developer community. Java is easy to learn, flexible, and has an open-source ecosystem. Java apps are compact and are easy to optimize. However, Java is a verbose language that requires more code, and with that comes a higher error risk.

What is Kotlin written in?

Current versions of Kotlin are written in Kotlin. Kotlin is also 100% interoperable with Java, and there’s major emphasis on making sure existing codebases can interact properly with Kotlin. You can easily call Kotlin code from Java and Java code from Kotlin.

What is kotlin good for?

Kotlin is usable for any kind of development work. That includes client-side, server-side, web, and Android. There’s also support for other platforms such as iOS. Kotlin is good for mobile and server-side applications, client-side with JavaScript or JavaFX, and data science. Thanks to Kotlin’s scripting capabilities, you can use it directly in your Gradle build scripts. Kotlin also supports modern programming concepts like extension functions, higher-order functions, and delegates.

Why is Kotlin in high demand?

Kotlin is in high demand because it is a modern, concise, and powerful language that makes development more enjoyable. Kotlin has quickly become the most popular programming language on Stack Overflow, and it's currently being used by companies such as Square, Pinterest, and Uber. Additionally, Android Studio includes full support for Kotlin development, which means that Android developers can now use Kotlin to write their apps. As Kotlin becomes more popular, we're likely to see even more companies begin using it in their projects. So if you're looking for a solution for your software project, learning Kotlin would be a wise decision.

What can you build with Kotlin?

You can build Android apps, server-side applications, and client-side web applications with Kotlin. It's also possible to use Kotlin for desktop applications and UWP apps. Kotlin is a Java Virtual Machine (JVM) language that interoperates well with Java. That means you can use Java libraries in Kotlin projects and vice versa. Additionally, the Kotlin compiler produces a bytecode that is compatible with the JVM. This makes it easy to use Kotlin in existing Java projects.
