# # `whereNotIn()`

The whereNotIn method filters the collection by a given key / value not contained within the given array:

    const collection = collect([
      { product: "Desk", price: 200 },
      { product: "Chair", price: 100 },
      { product: "Bookcase", price: 150 },
      { product: "Door", price: 100 }
    ]);

    const filtered = collection.whereNotIn("price", [150, 200]);

    filtered.all();

    //=> [
    //=>   { product: 'Chair', price: 100 },
    //=>   { product: 'Door', price: 100 },
    //=> ]

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