how to use the where clause in laravel to retrieve different categories of products in the same table

I am currently making an ecommerce site and am new to Laravel, and at the moment I'd like to retrieve data based on different categories from the same table, using a where clause to store the retrieved data in separate variables. The problem here is whenever I run this code it say undefined variable $newproducts. Below is my code. Thanks in advance

My Controller

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\product;

class ProductsController extends Controller
{
    public function index(){

        $allproducts=product::all();
        $bestsellerproducts=product::where('category','iphone 11')->get();
        $newproducts=product::where('category','iphone 12')->get();

        return view('test',['products'=>$allproducts],['bestsellerproducts'=>$bestsellerproducts],['newproducts'=>$newproducts]);
    }
    
}

My view Template

<!DOCTYPE html>
<html>
<head>
    <title>Test</title>
</head>
<body>


<h2>Best Seller products</h2>
@foreach($bestsellerproducts as $bestsellerproduct)

<label>Name</label>
{{ $bestsellerproduct['name'] }}

<label>Price</label>
{{ $bestsellerproduct['price'] }}

@endforeach<br>


<h2>New products</h2>
@foreach($newproducts as $newproduct)

<label>BaseName</label>
{{ $newproduct['name'] }}

<label>Price</label>
{{ $newproduct['price'] }}

@endforeach<br>


<h2>All products</h2>
@foreach($products as $product)

<label>BaseName</label>
{{ $product['name'] }}

<label>Price</label>
{{ $product['price'] }}

@endforeach<br>

</body>
</html>
