  // Insert all the elements of arr1 into arr2 beginning
  // at the index specified by n. We're using the spread
  // operator "..." to insert each individual element of 
  // arr1 instead of the whole array.
  combinedArrays.splice(n, 0, ...arr1)
  //                   (1, 0, ...[1, 2, 3])
  //                   [4, 1, 2, 3, 5, 6]
