Left Rotation

    :( I'm also stuck at test case 8. The message throws "Run time error" Don't know if there's any alternatives rather the traditional for / pop push method ? My current code (Pass all test cases except test case 8)

    function rotLeft(a, d) {
    let newArray = [...a];
    let iterationCount = 0;
    while(iterationCount < d){
        let valueToPop = newArray[0];
        newArray.shift();
        newArray.push(valueToPop);
        iterationCount++;
     }
    return newArray;
}
