function getEnvironmentData
Usage in Deno
```typescript import { getEnvironmentData } from "node:node__worker_threads.d.ts"; ```
getEnvironmentData(key: Serializable): Serializable
Within a worker thread, `worker.getEnvironmentData()` returns a clone
of data passed to the spawning thread's `worker.setEnvironmentData()`.
Every new `Worker` receives its own copy of the environment data
automatically.
```js
import {
Worker,
isMainThread,
setEnvironmentData,
getEnvironmentData,
} from 'node:worker_threads';
if (isMainThread) {
setEnvironmentData('Hello', 'World!');
const worker = new Worker(__filename);
} else {
console.log(getEnvironmentData('Hello')); // Prints 'World!'.
}
```
key: Serializable
Any arbitrary, cloneable JavaScript value that can be used as a {Map} key.
