What is the difference between a json resource & resource collection? in Laravel

Can someone explain the difference between a ResourceCollection and JsonResource?

In Laravel 6 docs you can generate 2 different types of resources... ResourceCollection and JsonResource. https://laravel.com/docs/6.x/eloquent-resources#resource-responses

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\ResourceCollection;

class ShopCollection extends ResourceCollection
{
    /**
     * Transform the resource collection into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return parent::toArray($request);
    }
}

vs ...

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;

class Shop extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return parent::toArray($request);
    }
}
