> WASI stands for WebAssembly System Interface. It's an API designed by the Wasmtime project that provides access to several operating-system-like features, including files and filesystems, Berkeley sockets, clocks, and random numbers, that we'll be proposing for standardization.

Am not expert, but here's the understanding I've picked up:
When you use JavaScript through Node, your JS gets the ability to open files and make network sockets and so on, because there are a set of APIs implemented by Node and exposed to your JS code, like so:
JS <-> native APIs <-> Node implementation of platform-specific operations
WASI applies to WebAssembly instead of JS. So again if we're on Node:
wasm <-> native APIs (WASI) <-> Node implementation of platform-specific operations
But WASI is much more general than Node's APIs, and meant to be used by different engines in different environments (browsers, native bindings, etc).
What is WASI?
