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 that Kotlin is the most popular language for Android development and is a popular replacement for Java on backend applications. It is also used for data science and for multiplatform, iOS, desktop, and web application development.
This book covers the essentials of Kotlin so you can start developing with this amazing programming language. It shows nearly everything you need to know in clear and executable code examples.
