Function forEach

forEach<T>(
    it: T[] | AsyncIterable<T, any, any> | Iterable<T, any, any>,
    fn: (v: undefined | T) => boolean | void | Promise<void> | Promise<boolean>,
    options?: Partial<ForEachOptions>,
): undefined | Promise<void>
Execute function f for each item in iterable. If f returns false, iteration stops.
```
forEach(iterable, v => {
 // do something with value
});
```
When using an async iterable, fn can also be async.
