## What it is
A robust JSONPath engine for Node.js that lets you query and manipulate JavaScript objects using JSONPath expressions. It supports the full JSONPath syntax including wildcards, recursive descent, slices, unions, and filter expressions.

## Use cases
- query nested JSON objects with JSONPath expressions
- extract values from deeply nested JSON data
- filter and select elements from JSON arrays
- traverse JavaScript object trees with path expressions
- find all values matching a path in a JSON document
- slice and index into JSON arrays declaratively

## When to choose
- you need a battle-tested, safe JSONPath implementation in Node.js
- you want full JSONPath syntax including script expressions and slices
- you need to query arbitrary JSON structures without writing manual traversal code

## When to avoid
- you only need simple property access that plain JavaScript dot notation handles
- you need JSONPath in the browser with a tiny bundle size
- you need JSONPath compliance with the newer RFC 9535 specification
