# `whereIn()`
|
||
|
|
|
||
|
|
The whereIn method filters the collection by a given key / value contained within the given array.
|
||
|
|
|
||
|
|
```js
|
||
|
|
const collection = collect([
|
||
|
|
{ product: 'Desk', price: 200 },
|
||
|
|
{ product: 'Chair', price: 100 },
|
||
|
|
{ product: 'Bookcase', price: 150 },
|
||
|
|
{ product: 'Door', price: 100 },
|
||
|
|
]);
|
||
|
|
|
||
|
|
const filtered = collection.whereIn('price', [100, 150]);
|
||
|
|
|
||
|
|
filtered.all();
|
||
|
|
|
||
|
|
// [
|
||
|
|
// { product: 'Chair', price: 100 },
|
||
|
|
// { product: 'Bookcase', price: 150 },
|
||
|
|
// { product: 'Door', price: 100 },
|
||
|
|
// ]
|
||
|
|
```

> When working with nested objects `whereIn()` method allows dot notated keys. E.g. `whereIn('product.categories', ['office-supplies', 'furniture'])`
