# `mergeRecursive()`
|
||
|
|
|
||
|
|
The mergeRecursive method merges the given array or collection recursively with the original collection. If a string key in the given items matches a string key in the original collection, then the values for these keys are merged together into an array, and this is done recursively:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect({
|
||
|
|
product_id: 1,
|
||
|
|
price: 100,
|
||
|
|
});
|
||
|
|
|
||
|
|
const merged = collection.mergeRecursive({
|
||
|
|
product_id: 2,
|
||
|
|
price: 200,
|
||
|
|
discount: false,
|
||
|
|
});
|
||
|
|
|
||
|
|
merged.all();
|
||
|
|
|
||
|
|
// {
|
||
|
|
// product_id: [1, 2],
|
||
|
|
// price: [100, 200],
|
||
|
|
// discount: false,
|
||
|
|
// }
|
||
|
|
```
