What Is Kotlin Good For?

Kotlin is a programming language that is relatively new to the scene. However, since its inception, it has been gaining popularity amongst developers worldwide. Kotlin is known to be an all-purpose language that can be used for various applications. The versatility of Kotlin makes it an ideal choice for developers, especially those who want to work on Android applications.

If you are wondering what Kotlin is good for, you have come to the right place. In this article, we will dive deep into the benefits of Kotlin and what it can do for you.

1. What is Kotlin?

Before we go any further, let’s start by understanding what Kotlin is. Kotlin is a statically typed programming language that was developed by JetBrains, the same company that created IntelliJ IDEA, the popular Java IDE. Kotlin was designed to be an alternative to Java and to address some of the shortcomings of Java.

Kotlin is an open-source language that is compatible with Java Virtual Machine (JVM). It is designed to be concise, safe, and interoperable with Java. Kotlin is a relatively new language, with its first official release in 2016. However, since its release, it has been gaining popularity amongst developers.

2. Advantages of Kotlin

Now that we know what Kotlin is let’s take a look at some of the advantages of using Kotlin.

2.1 Concise code

One of the primary advantages of using Kotlin is that it allows for concise code. Compared to Java, Kotlin requires less boilerplate code. Kotlin code is typically shorter and more readable than Java code.

2.2 Interoperable with Java

Kotlin is interoperable with Java. This means that Kotlin code can be used alongside Java code. Kotlin can call Java code and vice versa, making it easy to integrate Kotlin into existing Java projects.

2.3 Null Safety

Kotlin has a built-in null safety system. This means that Kotlin code is less prone to NullPointerExceptions. The null safety system ensures that developers cannot accidentally assign null values to variables.

2.4 Extension Functions

Kotlin allows for the creation of extension functions. This means that developers can add new functionality to existing classes without the need to modify the original class. Extension functions allow for code to be more modular and reusable.

2.5 Coroutines

Kotlin has built-in support for coroutines. Coroutines are a way of writing asynchronous code that is easier to read and write than traditional callback-based code.

2.6 Data Classes

Kotlin has built-in support for data classes. Data classes are classes that are used to hold data. Kotlin automatically generates equals(), hashCode(), and toString() methods for data classes. This makes it easier to work with data classes, especially when dealing with collections.

3. What is Kotlin used for?

Now that we know some of the advantages of Kotlin, let’s take a look at what Kotlin is used for.

3.1 Android Development

Kotlin is becoming increasingly popular for Android development. In 2019, Google announced that Kotlin is a preferred language for Android development. Kotlin is used alongside Java to develop Android applications.

3.2 Web Development

Kotlin can be used for web development. Kotlin can be used with popular web frameworks like Spring and Ktor. Kotlin can also be used to develop server-side applications.

3.3 Desktop Development

Kotlin can be used for desktop development. Kotlin has built-in support for JavaFX, a popular desktop application framework. Kotlin can be used to create cross-platform desktop applications.

3.4 Machine Learning

Kotlin can be used for machine learning. Kotlin has built-in support for numerical computation libraries like Koma and Nd4j. Kotlin can also be used to develop machine learning models using popular machine learning frameworks like TensorFlow.

3.5 Game Development

Kotlin can be used for game development. Kotlin can be used with popular game engines like LibGDX. Kotlin can also be used to develop game logic for games written in other languages.

4. How to get started with Kotlin

If you are interested in learning Kotlin, there are many resources available online. JetBrains, the creators of Kotlin, offer a free online course called Kotlin for Java Developers. The course is designed to teach Java developers how to use Kotlin. There are also many books and tutorials available online.

5. Final Thoughts

Kotlin is a versatile programming language that can be used for various applications. Kotlin is known for its concise syntax, null safety system, and interoperability with Java. Kotlin is becoming increasingly popular for Android development, web development, desktop development, machine learning, and game development. If you are a developer looking to learn a new language, Kotlin is definitely worth considering.
