## What it is
JSONStream is a Node.js streaming JSON parser that lets you pipe raw streams through JSONStream.parse() to emit parsed objects. It supports path-based queries so you can extract specific parts of large JSON documents incrementally.

## Use cases
- parse large JSON files without loading them into memory
- stream JSON API responses and process objects as they arrive
- extract nested fields from huge JSON documents with path expressions
- pipe HTTP responses through a JSON parser in Node.js
- process newline-delimited or array-based JSON incrementally

## When to choose
- you are on Node.js and need memory-efficient streaming JSON parsing
- you want to pipe parsed JSON objects directly into other streams
- you need to pull specific paths out of very large JSON documents

## When to avoid
- you need full JSON.parse semantics with strict validation
- you are not in a Node.js stream-based environment
- the project needs actively maintained dependencies (last release 2018)
