JSON 3 Polyfill

JSON 3 was a polyfill designed to provide `JSON.parse` and `JSON.stringify` functionality for older JavaScript environments that lacked native JSON support, specifically targeting ECMAScript 5 and earlier platforms (e.g., Internet Explorer 6-8). It adheres closely to the ECMAScript 5.1 specification, notably employing a recursive descent parser to avoid reliance on `eval`, a common security concern in early JSON implementations. The library's core differentiator was its robust, specification-compliant parsing and stringification for these legacy environments. However, it explicitly deviates from the spec regarding date serialization: it does not define `Date#toISOString()` or `Date#toJSON()`, instead handling date objects internally during `stringify()` operations, serializing them as simplified ISO 8601 strings. This approach aimed to preserve CommonJS compatibility and avoid polluting native prototypes. The project, last updated to version 3.3.3, is now explicitly deprecated and unmaintained. Developers are strongly advised against using it in new projects and should migrate existing applications to leverage the native `JSON` object available in all modern JavaScript environments. Its release cadence was irregular towards the end, as native JSON support became widespread. It was part of the BestieJS family, focusing on cross-platform support and specification adherence.
