WebAssembly code can be considered a structured stack machine; a machine where most computations use a stack of values, but control flow is expressed in structured constructs such as blocks, ifs, and loops. In practice, implementations need not maintain an actual value stack, nor actual data structures for control; they need only behave as if they did so.

WebAssembly is a programming language that has multiple concrete representations (its binary format and the text format). Both map to a common structure.

... this specification is complemented by additional documents defining interfaces to specific embedding environments such as the Web. These will each define a WebAssembly application programming interface (API) suitable for a given environment.

Its main goal is to enable high performance applications on the Web, but it does not make any Web-specific assumptions or provide Web-specific features, so it can be employed in other environments as well.

While the Web is the primary motivation for WebAssembly, nothing in its design depends on the Web or a JavaScript environment. It is an open standard specifically designed for embedding in multiple contexts, and we expect that stand-alone implementations will become available in the future.
