function permute(array, left = 0, right = array.length - 1) {
    if (left <= right) {

        console.log(array.toString());

        for (let i = left; i <= right; ++i) {

            let temp = array[i];
            array[i] = array[left];
            array[left] = temp;

            permute(array, left + 1, right);

            temp = array[i];
            array[i] = array[left];
            array[left] = temp;
        }
    }
}

const sequence = ["2", "3", "4"]
permute(sequence)
