javascript - clone an object's element and push to it's self -

i have object a.

if json.stringify(a), result:

{     "ordera": [{         "orderid": "19",         "serverid": 129,         "description": "apple",         "status": "1",         "details": ""     }] } 

now, clone it's own element , make larger object this:

{     "ordera": [{         "orderid": "19",         "serverid": 129,         "description": "apple",         "status": "1",         "details": ""     }],     "ordera": [{         "orderid": "19",         "serverid": 129,         "description": "apple",         "status": "1",         "details": ""     }],      "ordera": [{         "orderid": "19",         "serverid": 129,         "description": "apple",         "status": "1",         "details": ""     }] } 

how achieve using lodash/underscore/ or jquery?

so far, i've tried jquery.extend, lodash union, , didn't work.

object keys have unique, otherwise overwrite held data. see demo.

here's how:

var = {      "ordera": [{          "orderid": "19",          "serverid": 129,          "description": "apple",          "status": "1",          "details": ""      }]  };    ['b','c','d'].foreach(function(letter,index) {      all['order'+letter] = $.extend(true, {}, all.ordera);  });    console.log( json.stringify( ) );
