Learning a programming language is a daunting experience for many people, and not one that most individuals generally choose to undertake. As you have chosen to pick up this book, I assume that you have an interest in learning the Kotlin programming language and perhaps even becoming an expert at it someday. As a consequence, permit me to congratulate you on taking a bold step toward learning this language.
Regardless of the problem domain that you may wish to build solutions for, be it application development, networking, or distributed systems, Kotlin is a good choice for the development of systems to achieve the required solutions. In other words, a developer can't go wrong with learning Kotlin. At this point, a proper introduction to the Kotlin language is required.
Kotlin is a strongly-typed, object-oriented language that runs on the Java Virtual Machine (JVM) and can be used to develop applications in numerous problem domains. In addition to running on the JVM, Kotlin can be compiled to JavaScript, and as such, is an equally strong choice for developing client-side web applications. Kotlin can also be compiled directly into native binaries that run on systems without a virtual machine via Kotlin/Native. The Kotlin programming language was primarily developed by JetBrains – a company based in Saint Petersburg, Russia. The developers at JetBrains are the current maintainers of the language. Kotlin was named after Kotlin island – an island near Saint Petersburg.
Kotlin was designed to be used to develop industrial-strength software in many domains, but has seen the majority of its use come from the Android ecosystem. At the time of writing, Kotlin is one of the three languages that have been declared by Google as an official language for Android. Kotlin is syntactically similar to Java. As a matter of fact, it was designed to be a better alternative to Java. As a consequence, there are numerous significant advantages to using Kotlin instead of Java in software development.
