Tell us what’s happening:
What is causing the different output for both ? I think, both should produce the same output.
Your code so far
**1**
function frankenSplice(arr1, arr2, n) {
// It's alive. It's alive!
let arrCopy = arr2.slice();
arrCopy.splice(n, 0, ...arr1);
return arrCopy;
}
console.log(frankenSplice([1, 2, 3], [4, 5, 6], 1));
**2**
function frankenSplice(arr1, arr2, n) {
// It's alive. It's alive!
let arrCopy = arr2.slice();
let resultArr = arrCopy.splice(n, 0, ...arr1);
return resultArr;
}
console.log(frankenSplice([1, 2, 3], [4, 5, 6], 1));
