# `collapse()`
The collapse method collapses a collection of arrays into a single, flat collection:
```js
const collection = collect([[1], [{}, 5, {}], ['xoxo']]);
const collapsed = collection.collapse();
collapsed.all();
// [1, {}, 5, {}, 'xoxo']
```
```js
const collection = collect([[1, 2, 3], [4, 5, 6], [7, 8, 9]]);
const collapsed = collection.collapse();
collapsed.all();
// [1, 2, 3, 4, 5, 6, 7, 8, 9]
```
