method WASI.prototype.start
Usage in Deno
```typescript import { WASI } from "node:node__wasi.d.ts"; ```
WASI.prototype.start(instance: object): number
Attempt to begin execution of `instance` as a WASI command by invoking its `_start()` export. If `instance` does not contain a `_start()` export, or if `instance` contains an `_initialize()`
export, then an exception is thrown.
`start()` 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 `start()` is called more than once, an exception is thrown.
