# `intersectByKeys()`
|
||
|
|
|
||
|
|
The intersectByKeys method removes any keys from the original collection that are not present in the given `array` or collection:
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect({
|
||
|
|
serial: 'UX301',
|
||
|
|
type: 'screen',
|
||
|
|
year: 2009,
|
||
|
|
});
|
||
|
|
|
||
|
|
const intersect = collection.intersectByKeys({
|
||
|
|
reference: 'UX404',
|
||
|
|
type: 'tab',
|
||
|
|
year: 2011,
|
||
|
|
});
|
||
|
|
|
||
|
|
intersect.all();
|
||
|
|
|
||
|
|
// { type: 'screen', year: 2009 }
|
||
|
|
```
|
||
|
|
|
||
|
|
```js
|
||
|
|
const firstCollection = collect([1, 2, 3, 4, 5]);
|
||
|
|
const secondCollection = collect([1, 2, 3, 9]);
|
||
|
|
|
||
|
|
intersect = firstCollection.intersect(secondCollection);
|
||
|
|
|
||
|
|
intersect.all();
|
||
|
|
|
||
|
|
// [1, 2, 3]
|
||
|
|
```
