# `mapSpread()`
|
||
|
|
|
||
|
|
The mapSpread method iterates over the collection's items, passing each nested item value into the given callback.
|
||
|
|
The callback is free to modify the item and return it, thus forming a new collection of modified items:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
|
||
|
|
|
||
|
|
const chunks = collection.chunk(2);
|
||
|
|
|
||
|
|
const sequence = chunks.mapSpread((even, odd) => even + odd);
|
||
|
|
|
||
|
|
sequence.all();
|
||
|
|
|
||
|
|
// [1, 5, 9, 13, 17]
|
||
|
|
```
