WebAssembly will include both a binary notation, that compilers will produce, and a corresponding text notation, suitable for display in debuggers or development environments. – Ars Technica
Major Changes Ahead
Web Assembly walks away from the notion that the Web is a collection of documents.
With native code directly available to browsers the first “truly real web apps” will come about. We will enjoy a snappier web with richer functionality and enhanced security and the cost of porting interactive applications to the Web will be substantially reduced as companies refactor their existing C/C++ code bases with ease. Games, videos, office applications, interactive applets and animations will all benefit from this major improvement.
Web Assembly fills the gap of plugins on the Mobile Web.
In particular, the mobile Web will gain an astounding amount of functionality provided developers can figure out a way to make native applications take advantage of responsive interfaces. Except for security concerns this will probably be the greatest technological factor arriving in the Mobile Web in 2016.
