It provides a machine abstraction and hardware-agnostic instruction sets, where a high-level programming language can target the compilation to the Wasm instead of specific hardware architecture. The JavaScript engine implements the Wasm specification and recompiles the Wasm instruction to the target machine instruction where the program is executed. Technically, Wasm is similar to a popular virtual machine bytecode, such as Java Virtual Machine (JVM) or Microsoft Intermediate Language (MSIL). -

This makes it act like a desktop application - see Gmail, Flickr, Facebook, ... Rich Client programming in a web browser • Two choices: • Use a plug-in like Flash, Silverlight, Java, or ActiveX • Use the built-in JavaScript functionality of modern web browsers to access the native DOM (Document Object Model) of HTML5 compliant web browsers. -

Detecting Conflicts Among Declarative UI Extensions
Detecting Conflicts Among Declarative UI Extensions Benjamin S. Lerner Dan Grossman Brown University University of Washington [email protected] [email protected] Abstract shows a “Hello world” example written in XUL, a simple overlay We examine overlays, a flexible aspect-like mechanism for third- targeting it, and its composition with the base document. Appli- cations like Firefox use this ability heavily to modularize their UI party declarative extensions of declarative UIs. Overlays can be de- fined for any markup language and permit extensions to define new definitions into many smaller documents. Mozilla applications expose the overlay mechanism to third par- content that is dynamically woven into a base UI document. While powerful, overlays are inherently non-modular and may conflict ties and thereby enable a uniquely powerful extension mechanism. Such third party extensions can enhance or modify the program’s with each other, by defining duplicate or contradictory UI compo- nents. We construct an abstract language to capture core overlay se- base functionality in arbitrary ways; overlays are used to integrate mantics, and design an automatic analysis to detect inter-extension the extension’s UI into the existing UI. Moreover, end users can conflicts. We apply the analysis to a case study of Firefox exten- freely install extensions to customize their browser however they sions, finding several real-world bugs. Our analysis provides low- wish. This expressiveness has led to the widespread popularity level feedback to extension developers and high-level reports to end of Firefox extensions—hundreds of millions of users have down- users. Finally, we show how variants of overlays more expressive loaded extensions billions of times [13]. -
