Question

var merge = function(nums1, m, nums2, n) {

let first = m-1;

for(let i = n-1; i>=0;i-- )
    {
        if(nums1[first]>nums2[i])
            {
                  nums1.splice[first,0,nums2[i]]
            }
        else{ 
                nums1.splice(first+1,0,nums2[i])
        }
    }
nums1.splice(m+n-1)

You can use slice and concat

 const arr1= [1,2,3,0,0] const arr2 = [2,5,6] const n1 = 3 const n2 = 3 const merge = (arr1, n1, arr2, n2) => { return arr1.splice(0, n1).concat(arr2.splice(0, n2)).sort() } console.log(merge(arr1, n1, arr2, n2))
