Just experimenting with publishing a package

//Use the array methods slice and splice to copy each element of the first array into the second array, in order.Begin inserting elements at index n of the second array.The input arrays should remain the same after the function runs.

function array(arr1, arr2, n){
    let array2 = arr2.slice() 
    array2.splice(n, 0, ...arr1)
    return array2;
 }
console.log(array([3,4], [2,5,6,7,8], 1))
console.log(array([1, 2], ["a", "b"], 2))

 //slice() method to create a copy of arr2 so not to mutate original array
 //splice() to alter array and add the arr1 contents into array2 at starting index n, and not to delete any elements next arg is 0
