Some financial institutions have already opted in to a web stack for their internal tools, but the major complaint is that programming for the web isn't close enough to the metal. Webassembly is being design to make concerns about performance disappear.
Google, Microsoft, Mozilla and the engineers on the WebKit project today announced that they have teamed up to launch WebAssembly, a new binary format for compiling applications for the web. The web thrives on standards and, for better or worse, JavaScript is its programming language. Over the years, however, we’ve seen more and more efforts that allow developers to work around some of the limitations of JavaScript by building compilers that transpile code in other languages to JavaScript. Some of these projects focus on adding new features to the language (like Microsoft’s TypeScript) or speeding up JavaScript (like Mozilla’s asm.js project). Now, many of these projects are starting to come together in the form of WebAssmbly.
