[`json-joy`][json-joy] library implements cutting-edge real-time and
collaborative editing algorithms and other utilities for JSON data models.
Major focus of `json-joy` is development of the JSON CRDT protocol, a
Conflict-free Replicated Data Type that enables seamless
merging of changes in JSON data models, avoiding conflicts between replicas.

## Notable features
- Full JSON implementation as a CRDT (Conflict-free Replicated Datatype).
- The fastest list CRDT implementation in JavaScript.
- The fastest text OT (Operational Transformation) implementation in JavaScript.
- The fastest implementation of CBOR, DAG-CBOR, MessagePack, UBJSON, and JSON codecs in JavaScript.
- The fastest (HTTP) router implementation in JavaScript.
- The fastest JSON schema validation implementation in JavaScript.
- Very fast binary tree (Radix, AVL, Red-black\*, Splay) implementations in JavaScript.
- Very fast JSON Patch (and JSON Pointer) implementation in JavaScript, including many non-standard operations, and JSON Predicate implementation.
- Very fast JSON Expression implementation in JavaScript.
