    Use Cases & Benefits

    • Provides a high-performance JSON serialization and deserialization library for Go, accelerated by JIT compilation and SIMD instructions.
    • Delivers significantly faster JSON encoding and decoding than standard libraries by using runtime object binding without code generation and optimized memory usage.
    • Use for building low-latency Go services that require rapid JSON processing with minimal CPU overhead.
    • Use for streaming JSON encoding/decoding from io.Reader/io.Writer to handle large or multiple JSON values efficiently.
    • Use for manipulating JSON AST nodes directly to perform partial JSON queries, modifications, and validations without full unmarshaling.
