[WebAssembly][wasm-core] is a secure, sandboxed, portable runtime that runs inside and outside web browsers.
In practice:
- Languages (like JavaScript) compile to WebAssembly (
.wasmfiles) - WebAssembly runtimes (like [
wasmtime][wasmtime] or [jco][jco]) enable running WebAssembly binaries
While core WebAssembly has no access to things like the local filesystem or sockets, the [WebAssembly System Interface][wasi] steps in to enable defining a platform under WebAssembly workloads.
This means that with WASI, WebAssembly can operate on files, sockets, and much more.
