# `flatten()`
|
|
|
|
The flatten method flattens a multi-dimensional collection into a single dimension:
|
|
|
|
```js
|
|
const collection = collect({
|
|
club: 'Liverpool',
|
|
players: ['Salah', 'Firmino', 'Núñez'],
|
|
});
|
|
|
|
const flattened = collection.flatten();
|
|
|
|
flattened.all();
|
|
|
|
// ['Liverpool', 'Salah', 'Firmino', 'Núñez'];
|
|
```
|
|
|
|
You may optionally pass the function a "depth" argument:
|
|
|
|
```js
|
|
const collection = collect({
|
|
Apple: [
|
|
{
|
|
name: 'iPhone 6S',
|
|
brand: 'Apple',
|
|
},
|
|
],
|
|
Samsung: [
|
|
{
|
|
name: 'Galaxy S7',
|
|
brand: 'Samsung',
|
|
},
|
|
],
|
|
});
|
|
|
|
const flattened = collection.flatten(1);
|
|
|
|
flattened.all();
|
|
|
|
// [
|
|
// { name: 'iPhone 6S', brand: 'Apple' },
|
|
// { name: 'Galaxy S7', brand: 'Samsung' },
|
|
// ]
|
|
```
|
|
|
|
In this example, calling flatten without providing the depth would have also flattened the nested arrays, resulting in `['iPhone 6S', 'Apple', 'Galaxy S7', 'Samsung']`. Providing a depth allows you to restrict the levels of nested arrays that will be flattened.
