I wanted to clarify the cross-platform point:

WASM + WASI means a single binary has near-native performance, but can run on any CPU architecture and any OS.

To be even more specific: Webassembly is an abstract stack machine. There are no binary executables. You distribute the code in either the text or binary (`.wasm`) format, which is then executed by a runtime.

The runtime can be an interpreter or a (JIT) compiler. The latter can get you relatively close to native performance.
