- **Category:** Data Processing

- **Keywords:** array, nth, index, element, lodash

## Overview

Return the item at a specific index in the array.

**Highlights:**
- Uses lodash `_.nth`
- Supports negative indices (counting from the end)
- Returns a JSON-formatted value

**Example:**
- Array: `["a", "b", "c", "d"]`
- Index: `-1`
- Result: `"d"`

## Inputs

- **Array** (textarea): Enter a JSON array
- **Index** (number): Zero-based index (negative counts from the end)

## When to use

- When you need to extract a specific element from an array by its position.
- When working with arrays where negative indices are useful for counting from the end.
- When you want a quick, reliable way to access array elements without writing custom code.

## How it works

- Input a valid JSON array in the 'Array' field.
- Specify the index (zero-based, negative for reverse counting) in the 'Index' field.
- The tool uses lodash _.nth to fetch the item and outputs it as a JSON-formatted value.

## Use cases

- Extracting the last item from a list of logs or records for quick review.
- Accessing a specific element in an array of configuration settings during automation.
- Simplifying data extraction in scripts where array indices are dynamically determined.

## Frequently asked questions

### What does a negative index mean?

A negative index counts from the end of the array, where -1 is the last element.

### What happens if the index is out of bounds?

The tool returns undefined for indices beyond the array length.

### Can I use this with nested arrays or objects?

No, it works on a single-level array; for nested structures, use other data processing tools.

### Is the index zero-based?

Yes, indices start at 0 for the first element, and negative indices count from the end.

### What input format is required?

The array must be valid JSON, such as ["a", "b", "c"], and the index must be a number.
