CBOR (Concise Binary Object Representation) is a binary data serialization format designed for efficiency and interoperability. It's great for the constrained node environment. This JavaScript implementation offers encoding and decoding functionalities based on RFC 8949. It's often favored over JSON due to its smaller message size and efficient parsing capabilities, making it suitable for IoT and other applications where bandwidth is a constraint and processing power is minimal. It also offers deterministic encoding.
