Function each

each(
 data: I[] | Promise<I[]>,
 iterator: (item: I, token: CancellableToken) => Promise<void>,
 options?: EachOptions,
): CancellableHandle<void>
Iterates over a collection asynchronously for side effects.
Type Parameters
- I
 Item/value type in the collection.
Parameters
- data: I[] | Promise<I[]>
 Input array/object, or a promise that resolves to one.
- iterator: (item: I, token: CancellableToken) => Promise<void>
 Async callback invoked for each item/value.
- Optionaloptions: EachOptions
 Configuration options, including cancellation and concurrency.
Returns CancellableHandle<void>
A cancellable handle that resolves when iteration completes.
Example
```
const handle = each(
 [1, 2, 3],
 async (item, token) => {
 await token.sleep(5);
 console.log(item);
 },
 { concurrency: 2 },
);

await handle;
```
Example
```
const handle = each(
 { a: 1, b: 2 },
 async (value, key) => {
 console.log(key, value);
 },
);

await handle;
```
