Why

Developers are starting to push WebAssembly beyond the browser, because it provides a fast, scalable, secure way to run the same code across all machines.

But we don’t yet have a solid foundation to build upon. Code outside of a browser needs a way to talk to the system — a system interface. And the WebAssembly platform doesn’t have that yet.

What

WebAssembly is an assembly language for a conceptual machine, not a physical one. This is why it can be run across a variety of different machine architectures.
