returning an array in JavaScript returns [object] instead?

I'm attempting to return two arrays(multiple values) through declaring them as objects



<script>
    function funWithArrays(arr) {

        const arr1 = []; //short string
        const arr2 = []; //long string

        for (var i = 0; i < arr.length; i++) {
            if (arr[i].length <= 3) {
                arr1.push(arr[i]);
            } else {
                arr2.push(arr[i]);
            }
        }
        return {
            arr1,
            arr2
        };

    }
    document.getElementById("results").innerHTML = funWithArrays(["we", "cream", "to", "this", "two"]);

</script>

This is my attempt to do so, however, when I go to run it the output is as follows:

[object Object]

I'm wondering why the actual arrays aren't being returned?

You are returning incorrectly.

replace return {arr1, arr2} with return [...arr1, ...arr2] to return a single array.

Wrapping arrays in curly brackets( { } ) convert them into an object. Since you need to return an array, wrap your arrays in square brackets( [ ] ) instead.
