First: Thanks a lot for this awesome library!!!! It is a great help to decode and encode JSON objects and arrays!
Second: Problem
I am trying to generate a json object with an entry called "result". The content of "result" would be a keyword (firstString) and a description (secondString).
When I try:
DynamicJsonBuffer jsonBuffer;
JsonObject& root = jsonBuffer.createObject();
...
String req = httpClient.readStringUntil('\r');
...
root["result"] = "fail " + req;I get a long error list in Arduino IDE

Error compiling.If I use
DynamicJsonBuffer jsonBuffer;
JsonObject& root = jsonBuffer.createObject();
...
String req = httpClient.readStringUntil('\r');
...
String statResponse = "fail " + req;
root["result"] = statResponse;it works fine.
Any possibility to implement 'String Addition Operator' functionality? I am running out of memory in my project and would not like to add another String variable.
If it adds too much overhead on the library, I understand and will stick with a String variable to create the JSON entry.
