RX – a new random-access JSON alternative

REXC is a drop-in replacement for JSON.stringify and JSON.parse that produces 18x smaller output via binary encoding, de-duplicated strings, and shared schemas. It achieves 23,000x faster single-key lookups through O(log n) binary search on sorted indexes without any parse step, and creates near-zero heap pressure by returning a Proxy over a flat byte buffer. The library supports full JS interop including Object.keys, destructuring, and JSON.stringify, and ships with a CLI for converting between JSON and REXC formats.
