## What it is
A Node.js-based command-line utility belt for processing JSON and JavaScript, exposing underscore.js functions as simple one-liner commands. It supports chained pipelines for transforming structured data, similar to sed/awk/grep but for JSON.

## Use cases
- pretty-print and colorize JSON from the command line
- extract fields from JSON API responses in shell pipelines
- run JavaScript one-liners to transform JSON data
- chain commands to filter and pluck values from large JSON files
- replace awk/sed workflows when working with structured JSON

## When to choose
- you process JSON frequently in shell scripts and want JavaScript's expressiveness
- you need a quick pretty-printer or a full jq-like transformation pipeline in Node.js
- you're already familiar with underscore.js and want it on the CLI

## When to avoid
- you need a actively maintained tool with modern Node.js support and regular updates
- you prefer jq or other specialized JSON tools with larger communities
- you need to process non-JSON data formats
