What is Web Assembly and Why Should you Care?
summary
WebAssembly compiles languages into a portable binary that runs under a runtime like wasmtime runtime, demonstrated by a 16 MB ruby.wasm that executes a Ruby hello world with no host deps. Examples show TinyGo producing TinyGo compilation wasm modules, WASI providing file and socket access, and two-language linkage: a Go AES encrypt/decrypt module called from Rust, both loaded in Wasmtime and executed inside a Minecraft mod (Java) to open doors — it works end-to-end.
