WebAssembly

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine. Wasm is designed as a portable compilation target for programming languages, enabling deployment on the web for client and server applications.

WebAssembly and its platform targets

When talking about WebAssembly, one of the things that often confuses people is the lack of a great analogy for the various platform targets that WebAssembly supports. This ends up being a bit important as it dictates whether your WebAssembly code will (not) work with another bit as it all

A practical guide to WebAssembly memory | radu's blog

Memory in WebAssembly is one of the topics that creates confusion for newcomers, particularly for those with experience in languages with memory management features like garbage collection, such as JavaScript, Go, or Java. In this article we explore using memory in WebAssembly in various scenarios - passing JavaScript arrays to Rust and AssemblyScript modules, checking for some basic memory leaks using Valgrind, or exchanging strings between runtimes and modules using Wasmtime.
