What is Kotlin?

Kotlin is an open-source, statically typed programming language. It runs on the Java Virtual Machine (JVM) and also compiles to JavaScript. JetBrains, who made Kotlin,the company behind popular IDEs like IntelliJ IDEA, created Kotlin.  

The name comes from Kotlin Island, near St. Petersburg. Kotlin was designed to address common complaints about Java, such as verbose syntax, lack of functional programming support, and slow compile times.

Kotlin was first officially released in 2016. It has since grown incredibly popular, especially for Android development. Kotlin is now Google’s preferred language for Android apps. It continues to gain traction thanks to its concise and safe syntax, great tooling, and seamless interoperability with Java code.

Diving Deeper into Kotlin Features

Kotlin app development services are on the rise due to the growing popularity of the Kotlin coding language. Various Kotlin companies are offering their expertise in this modern programming language to provide comprehensive Kotlin software and web app development solutions. 

This surge can be attributed to its open-source nature, the same question “Is Kotlin open source?” is asked quite frequently and the answer is, indeed, Kotlin is an open-source programming language, appreciated among the community for its versatility in web development and beyond.

Smart Casts and Type Inference

One of Kotlin’s handy features is smart casts and type inference. The compiler can automatically infer types based on context without needing explicit declarations.

This avoids verbosity and makes code more fluid. The compiler will also warn if types cannot be confidently inferred. Overall, Kotlin cuts down on the ceremony of declaring types while still providing type safety.

Data Classes

For simple classes that hold data, Kotlin provides concise data classes. These come with auto generated implementations for methods like equals(), hashCode(), toString(), and more based on the property values.

Data classes avoid needing to exto write boilerplate code explicitly instance can be conveniently printed or checked for equality without any extra effort.

Sealed Classes

Kotlin’s sealed classes provide a way to model restricted class hierarchies when a value can have a limited set of types.

The seal restricts all subclasses to be declared in the same file. Com and combined when expressions, sealed classes enable exhaustiveness checking for logic handling the different cases.

Kotlin for Web Development

Kotlin mobile app development is particularly popular because it’s commonly used for Android apps underlining the question “What language are Android apps written in?” Major tech conglomerates like Google stand behind the Kotlin software development scene. Now, ‘Who developed Kotlin?’ you might ask. 

The language was developed by JetBrains, a renowned Kotlin company that has played a significant role in further promoting Kotlin software development.In addition to Android and backend development, Kotlin is great for building web apps.

Kotlin/JS for Frontend Web Apps

Kotlin can compile down to JavaScript code. This Kotlin/JS tooling allows writing frontend web applications entirely in Kotlin instead of JavaScript. You can access browser DOM APIs and build UIs with frameworks like React.Kotlin/JS offers a type-safe and concise alternative to raw JavaScript for frontends.

Kotlin for Server-Side Web Apps

On the server side, Kotlin works nicely with Java web frameworks like Spring Boot. But you can also use Kotlin-specific frameworks like Ktor for building high-performance asynchronous web apps.

Ktor provides a reactive, coroutine-based approach well-suited for Kotlin. There are also options like Vert.x that let you build non-blocking web services.

Kotlin Native

Kotlin Native compiles Kotlin directly to native binaries instead of bytecode. This allows sharing Kotlin code natively on platforms like iOS, embedded systems, Windows, and more.

The same Kotlin business logic can be compiled into a platform-specific binary executable that runs without needing a VM. Kotlin Native helps expand Kotlin’s reach beyond just the JVM.

Kotlin Multiplatform

A major advantage of Kotlin is the ability to share code across multiple platforms.

Sharing code across platforms allows the Kotlin multiplatform project to reuse code across servers, desktops, mobile, and more. You define common modules with shared business logic and then platform-specific parts.

For example, common domain models, validation logic, persistence interfaces, etc., can be reused across backends, Android, iOS, and the web. This avoids duplicating logic and saves significant development time.

Adoption and Community

Why use Kotlin, you may wonder? Kotlin’s uses expand from simpler, cleaner syntax to full interoperability with Java and Android, which makes it incredibly convenient for developers and offers an edge over other languages in mobile app development. 

Thus, an increasing number of Kotlin development services are emerging, serving the demand for Kotlin application development services. Be it a Kotlin app development company that’s creating a new application or a Kotlin programmer focused on improving an existing one; Kotlin is making its mark in the world of coding.

Kotlin User Base and Market Share

Originally focused on Android, Kotlin continues to grow in usage for backend and web development. On Stack Overflow, Kotlin went from the ~20th most popular tag in 2017 to consistently ranking in the top 10 today.

Google reported that over 60% of the top 1000 Android apps use Kotlin. It’s the preferred choice for new Android projects. Adoption is also growing on GitHub, with over 140,000 Kotlin repos to date. Kotlin provides a skills boost for modern full-stack developers.

Conferences and Resources

There are now several dedicated developer conferences like KotlinConf focusing on Kotlin. The language has an engaged community producing books, blogs, videos, and more learning materials.

Resources like Kotlin Koans, Kotlin Slack channels, Reddit forums, and the Kotlin podcast allow developers to connect and learn about effective practices using the language. The Kotlin Foundation continues to expand the language and tools.

Key Features and Benefits of Kotlin

What makes Kotlin stand out from other JVM languages like Java and Scala? Here are some of its most notable features:

Concise Syntax

Concise Syntax

Kotlin gets rid of a lot of the verbosity found in Java. Simple things require less code, improving developer productivity. For example, defining classes and methods is more compact. Kotlin also fully supports default and named function parameters, allowing you to omit common boilerplate code.

Functional Programming Support

Functional Programming Support

Kotlin is a multi-paradigm language incorporating object-oriented and functional programming features. It provides first-class support for concepts like lambdas, higher-order functions, lazy evaluation, and immutability. This allows for more declarative and concise code.

Null Safety

Null Safety

The billion dollar mistake that causes so many bugs? Not in Kotlin. Types are non-nullable by default. You have to declare something as nullable explicitly. The compiler will prevent common null pointer exceptions, boosting reliability.

Extension Functions

Extension Functions

You can extend existing classes with new functionality without having to inherit from them or use design patterns like Decorator. This helps keep your code more DRY.



Kotlin coroutines provide an efficient way to handle concurrency in asynchronous code. They offer a cleaner syntax compared to callbacks or locks. Coroutines boost performance and scalability for tasks like I/O-bound network calls.

Backward Compatible with Java

Backward Compatible with Java

A key advantage of Kotlin is that it's interoperable with existing Java code. Kotlin and Java classes can co-exist within a project. You can even call Java from Kotlin and vice versa. This makes adopting Kotlin incremental.

Android Development

Is Kotlin Right For Your Project?​

Is Kotlin Right For Your Project?

Kotlin offers many benefits for developers. But is it necessarily the best choice for your specific app or product?
Here are a few things to consider:

  • If you are building primarily for Android, Kotlin should almost always be the first choice, given Google’s strong recommendation.
  • For existing Java systems, switching entirely to Kotlin may be risky. But introducing it gradually can work well.
  • Make sure your team is comfortable learning some new language syntax and features if they don’t know Kotlin already.
  • Projects requiring the ultimate performance may want to stick with Java, but Kotlin is constantly improving.
  • If you desire a purely functional programming style, a language like Scala may suit your needs better than the more pragmatic Kotlin.
  • For smaller companies, developer availability may be better for Java. Kotlin’s skills still have some maturing to do.

Evaluate your specific needs, team skills, and constraints before deciding. Kotlin is a great choice for many modern applications but isn’t necessarily a golden hammer.
