Arrays: Left Rotation

    In js, I tried a different approach. In node.js, it has no difference in performance when it is compared to other approach.

    function rotLeft(a, d) {
    let i = 0, j = i + d;
    let arr = [];

    while (i < a.length) {
        if (j < a.length) {
            arr[i] = a[j];
            j++;
        } else {
		 j = 0;
        }
     i++;
    }
    return arr;
}
