# `diff()`
|
||
|
|
|
||
|
|
The diff method compares the collection against another collection or a plain array based on its values. This method will return the values in the original collection that are not present in the given collection:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect([1, 2, 3, 4, 5]);
|
||
|
|
|
||
|
|
const diff = collection.diff([1, 2, 3, 9]);
|
||
|
|
|
||
|
|
diff.all();
|
||
|
|
|
||
|
|
// [4, 5]
|
||
|
|
```
