Put anything into an array using Array.push()

var a=["Array Element"], b={"name": "MyObjName" };
a.push(b);    
// O/p : Array Element,[object Object]

now, you want to access name of b den you do this : 

 var a=["Array Element"], b={"name": "MyObjName" };
 a.push(b.name);    
 // O/p : Array Element,MyObjName

Likewise , if you have key : 

   var a=["Array Element"], b={"abc" :{"name": "MyObjName"} };
   a.push(b.abc.name);  
 // O/p : Array Element,MyObjName

Try:

arra['ddd'].push({
    'test1f': 'trtrtrt',
    'test13f': 'trtrtrt',
    'test14f': 'trtrtrt',
})

It adds items to js object. Then you can use it by typeing arra['ddd']['test1d'] or arra.ddd.test1d.

After assigning the array, you have to push to it instead of overwriting it:

arra['ddd'] = [];
arra['ddd'].push({
    'test1d': 'trtrtrt',
    'test13d': 'trtrtrt',
    'test14d': 'trtrtrt',
})
arra['ddd'].push({
    'test1f': 'trtrtrt',
    'test13f': 'trtrtrt',
    'test14f': 'trtrtrt',
})
