In my angular application i am getting an Json Data like below.

[{id:5,name:Immidiate},

{id:4,name:30 days},

{id:3,name:21 days},

{id:2,name:14 days},

{id:1,name:7 days},

{id:6,name:Custom}]

I need an output like below,

[{Name:5,Data:Immidiate},

{Name:4,Data:30 days},

{Name:3,Data:21 days},

{Name:2,Data:14 days},

{Name:1,Data:7 days},

{Name:6,Data:Custom}]

Here is my code

$rootScope.DashboardData[Name] =  widget.seriesname ;

delete $rootScope.DashboardData[widget.seriesname];                

$rootScope.DashboardData[data] =  widget.dataname ;

delete $rootScope.DashboardData[widget.seriesname];

widget.chartSeries = $rootScope.DashboardData;

where widget.seriesname is id and widget.dataname is name.

Problem: Key is not changed!

Use the map function:

var array = [{id:5,name:Immidiate},

{id:4,name:30 days},

{id:3,name:21 days},

{id:2,name:14 days},

{id:1,name:7 days},

{id:6,name:Custom}];



var resultArray = array.map(function(elm) {

   return { Name: elm[widget.seriesname], Data: elm[widget.dataname]};

});
