function types.isGeneratorObject
Usage in Deno
```typescript import { types } from "node:node__util.d.ts"; ```
isGeneratorObject(object: unknown): object is Generator
Returns `true` if the value is a generator object as returned from a
built-in generator function.
This only reports back what the JavaScript engine is seeing;
in particular, the return value may not match the original source code if
a transpilation tool was used.
```js
function* foo() {}
const generator = foo();
util.types.isGeneratorObject(generator); // Returns true
```
object is Generator
