Typically when you remove an index from an array, it reorders the indices. So for example if you have 4 items at index 0,1,2 and 3 and you remove index 2, 3 will become 2 and 3 itself will be removed or empty. Checking if Index 1 is valid means that the array is NOT empty which is what you were wanting. If Index 1 is NOT valid, then your entire array would be empty unless you’re somehow removing indices and not re-ordering the array, but I don’t think that’s possible.
