What Is Dart

This short, free ebook from March 2012 describes the Dart language, libraries, and tools that help you develop structured, fast, and maintainable web apps that run in any modern browser.

Dart is a class-based, object-oriented language that simplifies the development of structured modern apps, scales from small scripts to large applications, and can be compiled to JavaScript for use in any modern browser. In this rigorous but readable introductory text, Dart specification lead Gilad Bracha fully explains both the language and the ideas that have shaped it. The Dart Programming Language offers an authoritative description of Dart for programmers, computer science students, and other well-qualified professionals. The text illuminates key programming constructs with significant examples, focusing on principles of the language, such as optional typing and pure object-orientation. Bracha thoroughly explains reflection in Dart, showing how it is evolving into a form that programmers can easily apply without creating excessively large programs. He also shares valuable insights into Dart’s actor-style model for concurrency and asynchronous programming. Throughout, he covers both language semantics and the rationale for key features, helping you understand not just what Dart does, but why it works the way it does. You will learn about Dart’s object model, in which everything is an object, even numbers and Boolean values How Dart programs are organized into modular libraries How Dart functions are structured, stored in variables, passed as parameters, and returned as results Dart’s innovative approach to optional typing How Dart handles expressions and statements How to use Dart’s implementation of reflection to introspect on libraries, classes, functions, and objects Isolates and other Dart features that support concurrency and distribution Register your product at informit.com/register for convenient access to downloads, updates, and corrections as they become available.

Make Dart Your Programming Language of Choice There are many programming languages you can start learning today. But not many are as modern, easy to learn, object-oriented and scalable as Dart. Plus, combined with Flutter, Dart allows you to build native iOS, Android, web and desktop applications with a single code base. Dart Apprentice will teach you all the basic concepts you need to master this language. Follow along with the clearly and thoroughly explained concepts and you'll be building Dart applications in a breeze. Who This Book Is For Dart Apprentice is aimed at anyone interested in learning this new and modern programming language. If you're a beginner and want to start programming, this is great place to start. If you're an experienced programmer interested in learning Dart, here you'll find all the concepts you need to know. In either case, following along with this book, you'll be comfortable writing your own Dart programs in less time than you think. Topics covered in Dart Apprentice Expressions, Variables and Constants: The building blocks of the language Types and Operations: Static vs. dynamic typing, inference and strings Control Flow: Booleans, enums, switches, if statements and loops Functions: Named and anonymous functions, parameters and arrow syntax Classes: Objects, constructors, methods and properties Nullability: Null and how to handle it Collections: Lists, sets and maps Advanced classes: Inheritance, abstract classes, interfaces and mixins Asynchronous Programming: Concurrency, futures, streams and isolates One thing you can count on: after reading this book, you'll be prepared to build your own applications using Dart.

Summary Dart in Action introduces Google's Dart language and provides techniques and examples showing how to use it as a viable replacement for Java and JavaScript in browser-based desktop and mobile applications. It begins with a rapid overview of Dart language and tools, including features like interacting with the browser, optional typing, classes, libraries, and concurrency with isolates. After you master the core concepts, you'll move on to running Dart on the server and creating single page HTML5 web applications. About the Technology Dart is a web programming language developed by Google. It has modern OO features, just like Java or C#, while keeping JavaScript's dynamic and functional characteristics. Dart applications are "transpiled" to JavaScript, and they run natively in Dart-enabled browsers. With production-quality libraries and tools, Dart operates on both the client and the server for a consistent development process. About this Book Dart in Action introduces the Dart language and teaches you to use it in browser-based, desktop, and mobile applications. Not just a language tutorial, this book gets quickly into the nitty-gritty of using Dart. Most questions that pop up while you're reading are answered on the spot! OO newbies will appreciate the gentle pace in the early chapters. Later chapters take a test-first approach and encourage you to try Dart hands-on. To benefit from this book you'll need experience with HTML and JavaScript?a Java or C# background is helpful but not required. Purchase of the print book comes with an offer of a free PDF, ePub, and Kindle eBook from Manning. Also available is all code from the book.

Dart for Absolute Beginners enables individuals with no background in programming to create their own web apps while learning the fundamentals of software development in a cutting edge language. Easily digested chapters, while comprehensive enough to explore the whole domain, are aimed at both hobbyists and professionals alike. The reader will not only gain an insight into Dart, but also the technologies behind the web. A firm foundation is laid for further programming studies. Dart is a new, innovative language developed by Google which is poised to take the web by storm. For client side web app development, Dart has many advantages over JavaScript. These include but are not limited to: improved speed, enforcement of programmatic structure, and improved facilities for software reuse. Best of all, Dart is automatically converted to JavaScript so that it works with all web browsers. Dart is a fresh start, without the baggage of the last two decades of the web. Why start learning to program with yesterday’s technology? Teaches you the fundamentals of programming and the technologies behind the web. Utilizes the cutting edge, easy to learn, structured Dart programming language so that your first steps are pointed towards the future of web development. No prior knowledge is required to begin developing your own web apps.
