## Description

go-json is a high-performance JSON serialization library for Go that serves as an encoder and decoder replacement for the standard library. It provides tools to convert native data structures to and from JSON format with optimized processing speeds.

The library includes a conditional serializer for filtering specific data structure fields during the encoding process and a colorizer to produce color-coded JSON strings for human readability.

The project supports context-aware marshaling to trigger specific logic during the serialization of complex data types.
