# whereIn()

The whereIn method filters the collection by a given key / value 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.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'])
