method WASI.prototype.initialize
Usage in Deno
```typescript import { WASI } from "node:node__wasi.d.ts"; ```
WASI.prototype.initialize(instance: object): void
Attempt to initialize `instance` as a WASI reactor by invoking its `_initialize()` export, if it is present. If `instance` contains a `_start()` export, then an exception is thrown.
`initialize()` requires that `instance` exports a [`WebAssembly.Memory`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/WebAssembly/Memory) named `memory`.
If `instance` does not have a `memory` export an exception is thrown.
If `initialize()` is called more than once, an exception is thrown.
