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'])
