## Overview

Slice a JSON array using start and end indices.

**Highlights:**
- Uses lodash `_.slice`
- Supports negative indices
- Returns the sliced array as JSON

**Example:**
- Array: `["a", "b", "c", "d"]`
- Start: `1`
- End: `3`
- Result: `["b", "c"]`

## Inputs

- **Array** (textarea): Enter a JSON array
- **Start Index** (number): Index to start slicing (supports negative)
- **End Index** (number): Index to stop slicing (exclusive)

## When to use

- When you need to extract a specific range of elements from a JSON array.
- When working with arrays where indices might be negative, such as getting the last few items.
- When automating data processing tasks that involve array manipulation.

## How it works

- Input a valid JSON array into the designated textarea field.
- Specify the start index (default is 0) and optionally the end index (exclusive).
- The tool applies lodash _.slice to the array based on the provided indices.
- It returns the sliced array as a JSON string for further use.

## Use cases

- Extracting a subset of data from a large JSON array for analysis.
- Handling API responses where only a portion of the array is needed.
- Preparing array data for further processing in scripts or applications.

## Frequently asked questions

### What is the default value for the start index?

The default start index is 0.

### Can I use negative indices?

Yes, negative indices are supported, counting from the end of the array.

### What happens if I don't specify an end index?

If end is not specified, the slice goes to the end of the array.

### Is the input array validated?

The tool expects a valid JSON array; invalid input may cause errors.

### In what format is the result returned?

The result is returned as a JSON array string.
