## Description

This project is a high-performance JSON library for Go, serving as a replacement for the standard encoding/json package. It provides a serialization engine for encoding and decoding data structures, alongside a schemaless parser for extracting specific values from JSON blobs using paths.

The library distinguishes itself through a focus on reducing CPU and memory overhead. It implements a high-performance encoder that utilizes buffer reuse and reduced float precision to increase data throughput.

Broad capability areas include data serialization, high-performance JSON processing, and schema-less value extraction. The engine supports nested value extraction and property verification without requiring predefined data schemas.
