Kotlin Essentials (2022) True PDF, ePUB This book covers the essentials of Kotlin so you can start developing with this amazing programming language. We show nearly everything you need to know in clear and executable code examples. Kotlin is a powerful language, largely thanks to its expressive syntax, intuitive and null-safe type system, and great tooling support. It’s no wonder Kotlin is the most popular language for Android development and is a popular alternative to Java for backend applications. It is also used for data science and for multi platform, iOS, desktop, and web application development. In this book, you are going to learn about the most important Kotlin features, which will let you properly start your adventure with Kotlin. Kotlin is a multiplatform language, but it is mainly used on JVM. Also, most Kotlin developers have experience in Java. This is why I sometimes reference Java and its platform, and I sometimes present JVM-specific elements.
