Can anyone help me understand why I encountered an error message when trying to loop over an array using a for..in loop to display the index of each item? I'm looking for advice on how this process actually works. Thanks!

If you are working with arrays, it's important to note that you should use for...of
instead of for...in
as the latter is meant for iterating over objects.
However, keep in mind that for...of
will only provide you with the value, not the index.
To access both the value and index, utilize forEach
like so:
array.forEach(function (value, index) {
});
