WebAssembly (abbreviated Wasm) is a binary
instruction format for a stack-based virtual
machine. Wasm is designed as a portable
target for compilation of high-level languages
like C/C++/Rust, enabling deployment on the
web for client and server applications.

High-Level Goals
• Define a portable, size- and load-time-efficient
binary format to serve as a compilation target
which can be compiled to execute at native speed
by taking advantage of common hardware
capabilities available on a wide range of
platforms, including mobile and IoT.
• Design to support non-browser embeddings as
well.

High-Level Goals
Design to execute within and integrate well with
the existing Web platform:
• execute in the same semantic universe as
JavaScript; allow synchronous calls to and
from JavaScript
• access browser functionality through the same
Web APIs that are accessible to JavaScript
