Median of Two Sorted Arrays

example 1:

input: nums1 = [1,3], nums2 = [2]
output: 2.00000
explanation: merged array = [1,2,3] and median is 2.
example 2:

input: nums1 = [1,2], nums2 = [3,4]
output: 2.50000
explanation: merged array = [1,2,3,4] and median is (2 + 3) / 2 = 2.5.

var findMedianSortedArrays = function(nums1, nums2) {
 const toltalLength = nums1.length + nums2.length;let x = 0;

for(let i=0; i< toltalLength;i++){

if(x> nums1.length -1){  nums2.splice(0, y)
     mergedArr.push(...nums2)
      break; }

       if(y> nums2.length -1){
            nums1.splice(0, x)
            mergedArr.push(...nums1)
