JsonObjectConst
Description
JsonObjectConst is a read-only version of JsonObject.
It’s also twice smaller because it doesn’t contain a pointer to the memory pool.
Example
JsonDocument doc;
// deserialize the object
char json[] = "{\"hello\":\"world\"}";
deserializeJson(doc, json);
// extract the data
JsonObjectConst object = doc.as<JsonObject>();
const char* world = object["hello"];
