Why quick sort is always slower than bubble sort in my case?

They use same array:

QUICK SORT Time: 3159 miliseconds (array length 10K)

Bubble SORT Time: 1373 miliseconds (array length 10K)

I’m trying to compare time of the sorting using quick and bubble sort algoritms. I use the array with 10K different random numbers sorted in random order for both functions. But for some reason bubble sort is always sort array faster than quick sort, even if average time complexity of bubble sort is worse than average time complexity of quick sort. Why bubble sort algorithms slower than quick sort algorithm in my case? (I tried different lengths of array, from 10 to 10K)

Thats my quick sort function

let quickSort = (arr) => {
    if (arr.length <= 1) {
        return arr
    }
    const pivot = arr[0]
    const rest = arr.slice(1);
    let left = [],
        right = [];
    rest.forEach(el => el > pivot ? right = [...right, el] : left = [...left, el]);
    return [...quickSort(left), pivot, ...quickSort(right)];
}

And that’s my bubble sort function

let bubbleSort = (arr) => {
    for (let i = 0; i < arr.length; i++) {
        for (let s = i + 1; s < arr.length; s++) {
            if (arr[s] < arr[i]) {
                let a = arr[i];
                arr[i] = arr[s]
                arr[s] = a;
            }       
        }
    }
    return arr
}
