Tool usage guide
The Nth Item tool retrieves the element at a specified index from a JSON array using the lodash _.nth function. It supports both positive and negative indices, allowing you to access items from the start or end of the array and returns the value in JSON format.
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.
Background
Processing a list of user-submitted answers where the third answer is critical for analysis.
Problem
Need to consistently extract the third element without manual indexing each time.
How to use
Input the array of answers, e.g., ["yes", "no", "maybe", "unknown"], and set the index to 2.
Outcome
The third answer "maybe" is retrieved and displayed in JSON format.
A negative index counts from the end of the array, where -1 is the last element.
The tool returns undefined for indices beyond the array length.
No, it works on a single-level array; for nested structures, use other data processing tools.
Yes, indices start at 0 for the first element, and negative indices count from the end.
The array must be valid JSON, such as ["a", "b", "c"], and the index must be a number.
