The term, in context
AI-assisted draft · approved dataset
The WebAssembly Component Model is a packaging and interface standard layered on top of core WebAssembly modules that gives compiled binaries language-agnostic, strongly typed interfaces. It uses an interface-definition language to declare the functions and data types a component imports and exports, and a standardized calling convention that lets a component built in one source language call one built in another without hand-written glue code.
