Function partition

partition(
 data: I[] | Promise<I[]>,
 predicate: (item: I, token: CancellableToken) => Promise<boolean>,
 options?: PartitionOptions,
): CancellableHandle<[I[], I[]]>
Splits a collection into two arrays based on an async predicate. Returns a tuple [truthy[], falsy[]] where truthy contains items that passed the predicate and falsy contains items that failed.
Type Parameters
- I
 The input item type.
Parameters
- data: I[] | Promise<I[]>
 Input collection, or a promise that resolves to one.
- predicate: (item: I, token: CancellableToken) => Promise<boolean>
 Async predicate to evaluate each item.
- Optionaloptions: PartitionOptions
 Configuration options including cancellation and concurrency.
Returns CancellableHandle<[I[], I[]]>
A cancellable handle resolving to [truthy[], falsy[]].
Example
```
const handle = partition(
 [1, 2, 3, 4, 5],
 async (item) => item % 2 === 0,
);

const [evens, odds] = await handle; // [[2, 4], [1, 3, 5]]
```

 data: CollectionInput | Promise<CollectionInput>,
 predicate: (
 item: I,
 key: string | number,
 token: CancellableToken,
 ) => Promise<boolean>,
 options?: PartitionOptions,

Splits a collection into two arrays based on an async predicate. Returns a tuple [truthy[], falsy[]] where truthy contains items that passed the predicate and falsy contains items that failed.
Type Parameters

 The input item type.
Parameters
- data: CollectionInput | Promise<CollectionInput>
 Input collection, or a promise that resolves to one.
- predicate: (item: I, key: string | number, token: CancellableToken) => Promise<boolean>
 Async predicate to evaluate each item.
- Optionaloptions: PartitionOptions

Returns CancellableHandle<[I[], I[]]>
A cancellable handle resolving to [truthy[], falsy[]].
