Slice and Splice - Spread Operator?

Tell us what’s happening:
Hi guys! So as you can see, I thought that perhaps I could use the spread operator as the last argument in splice, but it doesn’t appear to have worked. I think the slice stage seems to be working from a console.log I did but I can’t seem to figure out why splice isn’t working. Console.logging the splice instead of returning it just shows that I’ve created an empty array :confused:

Any pointers would be much appreciated!

Your code so far

function frankenSplice(arr1, arr2, n) {
var why = arr2.slice();
return why.splice(n, 0, ...arr1);


frankenSplice([1, 2, 3], [4, 5], 1);

Link to the challenge:

Return value

An array containing the deleted elements

from MDN - Splice

It’s working, you just have to return the array after the splice, not return the value returned by splice itself :slight_smile:

Ahhh. Thank you for that. I’ve been trying to figure this out for over an hour :sweat_smile:
