Dart is a programming language for developing web applications created by Google. It offers modern object-oriented features like Java or C# without sacrificing JavaScript's inherent dynamism and functional programming focus. Applications written in Dart are translated to JavaScript, but can also be executed directly in browsers that support Dart. Dart comes with industry-quality libraries and tools. Dart can be used to write both a client- and server-side application, simplifying the development process. In this book, you will become familiar with the Dart language and learn how to use it to create applications that run in the browser, on desktop or mobile OS. This is not just a tutorial on the language, but rather quickly the author gets into the technical aspects of working with Dart. Most questions that arise while reading are answered immediately! The publication is intended for web programmers of various qualifications, including those unfamiliar with object-oriented programming.
