|

|
|
|
||
|
|
The crossJoin method cross joins the collection with the given array or collection, returning all possible permutations:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect([1, 2]);
|
||
|
|
|
||
|
|
const joined = collection.crossJoin(['a', 'b']);
|
||
|
|
|
||
|
|
joined.all();
|
||
|
|
|
||
|
|
// [
|
||
|
|
// [1, 'a'],
|
||
|
|
// [1, 'b'],
|
||
|
|
// [2, 'a'],
|
||
|
|
// [2, 'b'],
|
||
|
|
// ]
|
||
|

```
