# `diffKeys()`
|
||
|
|
|
||
|
|
The diffKeys method compares the collection against another collection or a plain object based on its keys. This method will return the key / value pairs in the original collection that are not present in the given collection:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect({
|
||
|
|
a: 'a',
|
||
|
|
b: 'b',
|
||
|
|
c: 'c',
|
||
|
|
d: 'd',
|
||
|
|
});
|
||
|
|
|
||
|
|
const diff = collection.diffKeys({
|
||
|
|
b: 'b',
|
||
|
|
d: 'd',
|
||
|
|
});
|
||
|
|
|
||
|
|
diff.all();
|
||
|
|
|
||
|
|
// { a: 'a', c: 'c' }
|
||
|
|
```
