return array instead of objects laravel/javascript ajax call

I am creating a front-end Vue component. For this I am using data and a database from a Laravel project. The problem I got is that a method from Laravel (And so does the AJAX call) is returning an Array, which is good, and the other method is returning just the objects (collection?) with the AJAX call. I need both calls returning an Array because I am using some Array functions in my component.

I've tried all sort of things, both on the front-end as back-end. I've tried on the backend to let laravel return an array and on the Front-end I tried to set the objects to an array. Both didn't succeed.

My JS code (And AJAX calls)

    methods: {

        countAllItems() {
            this.countItems = this.items.length;
        },

        getUrl(items) {

            let results = items;

            results.forEach((item) => {

                let id = item.id;

                return item.url = `/advertisements/show/${id}`;
            });

        },

        getMax(items) {

            let boats = items.slice(0, 4);

            this.items = boats;

            this.getUrl(this.items);
            this.countAllItems();

        },

        getBoats() {

            axios.get('/api/boats')
                .then((response) => {

                    //this will return an array
                    console.log(response.data);
                    this.items = response.data;

                    this.countAllItems();
                    this.getMax(this.items);




                })
                .catch((error) => console.log(error));

        },

        getReservations() {

            axios.get('/api/popular')
                .then((response) => {

                    //this will return objects, and must be an array
                    console.log(response.data);
                    this.items = response.data;

                    this.countAllItems();
                    this.getMax(this.items);

                });
        }

    },

    created() {
        this.getBoats();
        this.getReservations();
    }

The back-end

//This will return the array
public function boats() {

    return Boat::with('media')->get();

}

//This will return objects
public function messages() {

    $boats = Boat::with('media')->get()->sortByDesc(function($boat) {
        return count($boat->conversations);
    });

    return $boats;

}

Is there someone who can help me out? So I need either a fix for returning an array in the Laravel method, or something like a function to push both objects to an array in JavaScript.

Edit

So I tried some things and doing that something occured to me. When I do dd($boats) it will return a Collection. When I do dd($boats->toArray) it returns an array. What the weird thing is is that it makes no difference tho in the AJAX calls. So $boats->toArray() will still return only the objects and not the objects in an array.

I also tried to push the objects in an array but that doesn't work either. It will place the collection (as a object) into an array. How can I change this that the objects will directly be inserted in the array instead of the collection as a object?

let arr = [];

arr.push(response.data);

console.log(arr);
