Chapter 1: Getting started with dart

Remarks

Dart is an open-source, class-based, optionally-typed programming language for building web applications--on both the client and server--created by Google. Dart's design goals are:

? Create a structured yet flexible language for web programming. ? Make Dart feel familiar and natural to programmers and thus easy to learn. ? Ensure that Dart delivers high performance on all modern web browsers and environments

ranging from small handheld devices to server-side execution.

Dart targets a wide range of development scenarios, from a one-person project without much structure to a large-scale project needing formal types in the code to state programmer intent.

To support this wide range of projects, Dart provides the following features and tools:

? Optional types: this means you can start coding without types and add them later as needed.

? Isolates: concurrent programming on server and client ? Easy DOM access: using CSS selectors (the same way that jQuery does it) ? Dart IDE Tools: Dart plugins exist for many commonly used IDEs, Ex: WebStorm. ? Dartium: a build of the Chromium Web Browser with a built-in Dart Virtual Machine
