Walrath K., Ladd S. Dart: Up and Running

O’Reilly Media/Google Press, 2012. — 158 p. — ISBN: 978-1-449-33089-7.Dart: Up and Running is a practical guide that introduces the Dart programming language and teaches you how to build Dart applications.
The goal of Dart is "ultimately to replace JavaScript as the lingua franca of web development on the open web platform. Dart is intended to solve JavaScript's problems (which, according to a leaked memo, cannot be solved by evolving the language) while offering better performance, the ability "to be more easily tooled for large-scale projects" and better security features.Google is also working on Dart to help it build more complex, full-featured client-side Web apps. Dart is a class-based, single inheritance, object-oriented language with C-style syntax. It supports interfaces, abstract classes, reified generics, and optional typing. Static type annotations do not affect the runtime semantics of the code. Instead, the type annotations can provide documentation for tools like static checkers and dynamic run time checks.
