The answer
The safest method is to add a Guard Clause (e.g., if array.length == 0 return) at the very beginning of your function to exit before the loop evaluates.

How should I handle empty arrays?
More FAQs in Handling Edge Cases at the Start and End of a Loop
An edge case refers to the extreme boundaries of the data, such as the very first element, the very last element, or processing an entirely empty array.
When the loop reaches the final element of the array, i+1 points to an index that does not exist, triggering an Index Out of Bounds exception.
Adjust the loop boundaries. If checking i+1, ensure the loop stops at length-1. If checking i-1, ensure the loop starts at index 1.
