## What it is
Douglas Crockford's original JSON library for JavaScript, providing JSON.stringify and JSON.parse via 2.js for environments lacking a built-in JSON object, plus cycle.js for encoding cyclical structures. It is now largely historical since JSON is built into modern JavaScript engines.

## Use cases
- parse JSON strings in old browsers like IE8
- serialize JavaScript objects to JSON
- encode cyclical object structures in JSON
- recover decycled JSON back into object graphs
- polyfill the JSON global object

## When to choose
- you must support legacy browsers without native JSON support
- you need to serialize objects containing circular references or DAGs

## When to avoid
- targeting only modern browsers or Node.js, which have built-in JSON
- you need high-performance or streaming JSON parsing
- you need a maintained library with a license file

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, parser
- domain: developer-tools, web-development, apis
- platform: browser
- tags: legacy-browsers, crockford, cyclical-references, nodejs
