Array rotation solution

/**
* @param {number[]} nums
* @param {number} k
* @return {void} Do not return anything, modify nums in-place instead.
*/
// using unshift and pop method (Good for first run)
var rotateByUnshift = function(nums, k) {
  k = k > nums.length ? k - nums.length : k;
  for(var i=0;i<k;i++){
    nums.unshift(nums.pop());
  }
  return nums;
};

// using prototype unshift, slice, and apply (Accepted)
var rotateByApply = function(nums, k) {
  k %= nums.length;
  if (k !== 0){
    var tmp = nums.slice(-k);
    nums.splice(-k, k);
    Array.prototype.unshift.apply(nums, tmp);
  }
  return nums;
};

// console.log(rotateByUnshift([7,2,1,3,4,5], 3))
// console.log(rotateByApply([7,2,1,3,4,5], 3))
