Append objects in loop

I've chunks of data coming as response of each call and is retrieved as parameter of a function in below format. I need to append all the chunks of data into one. 

function getJSONdata(jsondata){
//Below is where I need help
//cumilatedJSONdata = cumilatedJSONdata + jsondata
}

Below is the Format of the objects coming:

var jsondata = {"results":[
{"code":"1101696","name":"1101696","price":{"formattedValue":"36.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}}
]};

I want the cumilatedJSONdata structure should be something like

var cumilatedJSONdata = {"results":[
{"code":"1101696","name":"1101696","price":{"formattedValue":"36.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}},
{"code":"1101693","name":"1101693","price":{"formattedValue":"33.00 
CAD"}},
{"code":"1101699","name":"1101699","price":{"formattedValue":"39.00 
CAD"}}
]};

I tried something like this 

var cumilatedJSONdata= {"results":[]}

function getJSONdata(jsondata){
var cumilatedJSONdata = $.extend(true,cumilatedJSONdata, jsondata
}
 );

This is not persisting previous data and getting replaced with new data.

Could anyone please help me on this.

You can try using the concat method of javascript

cumilatedJSONdata.results = cumilatedJSONdata.results.concat(jsondata.results);

let results = [];

// do your async loop / promise loop here
while (needToGetResults) {
    let newResponse = await asyncRequest();
    results = results.concat(newResponse.results);
}

return results;

alternatively,

return {results:results}
