# `Selecto.Advanced.JsonOperations`

JSON operations support for PostgreSQL JSON and JSONB functionality.

Provides comprehensive support for JSON path queries, aggregation, manipulation,
and testing functions. Works with both JSON and JSONB column types with 
automatic type detection and optimization.

## Examples

    # JSON path extraction
    selecto
    |> Selecto.select([
        {:json_extract, "metadata", "$.category", as: "category"},
        {:json_extract, "metadata", "$.specs.weight", as: "weight"}
      ])
    
    # JSON aggregation
    selecto
    |> Selecto.select([
        {:json_agg, "product_name", as: "products"},
        {:json_object_agg, "product_id", "price", as: "price_map"}
      ])
    |> Selecto.group_by(["category"])
    
    # JSON filtering
