objectNode.put("age", 30);
objectNode.put("isStudent", true);
objectNode.put("scores", 6.2);

// Retrieve a property value
var name = objectNode.get("name").toString();
var age = objectNode.get("age").asInt();
var isStudent = objectNode.get("isStudent").asBoolean();
var scores = objectNode.get("scores");

// Remove a property
objectNode.remove("age");

// Check if a property exists
var hasAge = objectNode.has("age");

// Get the number of properties
var numProperties = objectNode.size();

// Clear all properties
objectNode.clear();

// Check if the object is empty
var isEmpty = objectNode.isEmpty();

// Get the JSON representation
var jsonString = objectNode.toString();
