SproutCore 135 SproutCore A demo application of SproutCore Developer(s) Sproutit, Apple Inc. and community. Initial release 2010 Stable release 1.0.1046 / March 19, 2010 Development status Active Written in Ruby/JavaScript Operating system Cross-platform License MIT License Website http://www.sproutcore.com/ SproutCore is an open-source JavaScript framework. Its goal is to allow developers to create web applications with advanced capabilities and a user experience comparable to that of desktop applications. When developing a SproutCore application, all code is written in JavaScript (including the view layer in 1.0). SproutCore, initially created in 2007 by Sproutit as the basis for their Mailroom application, is available under the MIT License. Apple announced MobileMe at WWDC in 2008, noting that much of it was built using SproutCore. Apple has contributed greatly to the project as part of a Web 2.0 initiative. SproutCore is also used at iWork.com, the online extension of the iWork productivity software by Apple. Latest stable SproutCore release is 1.0, a major milestone with significant improvements, and was released on March 19th in 2010 [1] . SproutCore implements some CommonJS specifications in the upcoming 1.1 release [2] . Notes • "Apple adopting SproutCore for web applications" [3] .

Though the term is not formally defined, its basic principles are generally understood to include: • Separation of functionality (the "behavior layer") from a Web page's structure/content and presentation [1] • Best practices to avoid the problems of traditional JavaScript programming (such as browser inconsistencies and lack of scalability) • Progressive enhancement to support user agents that may not support advanced JavaScript functionality [2] The need for a new paradigm JavaScript historically has had a reputation for being a clumsy, hackish language unsuitable for serious application development. [3] [4] This has been largely due to inconsistent implementations of the language itself and the Document Object Model [5] in various browsers, and the widespread use of buggy cut-and-paste code. Runtime errors were so common (and so difficult to debug) that few programmers even tried to fix them, as long as the script behaved more or less the way it was supposed to; [6] scripts often failed completely in some browsers. The recent emergence of standardized browsers, JavaScript frameworks and high-quality debugging tools have made organized, scalable JavaScript code possible, and the emergence of AJAX interfaces has made it essential. Whereas JavaScript was once reserved for relatively simple and non-critical tasks such as form validation and decorative novelties, it is now being used to write large, complex codebases that are often part of a site's core functionality. Run time errors and unpredictable behavior are no longer minor annoyances; they are fatal flaws. Advocates of Unobtrusive JavaScript see it as part of the larger Web standards movement; much as the demand for cross-browser compatibility has driven the increasing emphasis on standardized markup and style, the increasing demand for rich Internet applications is driving the movement toward better practices with the use of JavaScript. The concept of Unobtrusiveness in relation to JavaScript programming was coined in 2002 by Stuart Langridge [7] in the article "Unobtrusive DHTML, and the power of unordered lists [8] ". [9] In the article Langridge argues for a way to
