1. Retrieve Last Transaction
Background
You have an array of recent transaction amounts and need the most recent one for a summary.
Problem
Manually counting indices to find the last element is error-prone and time-consuming.
How to use
Enter the transaction array, e.g., [50, 75, 100, 125], and set the index to -1.
Outcome
The tool returns 125, the last transaction amount, as a JSON value.
