Change structure of JS array [duplicate]

Question

i am a beginner in javascript and i have a litle problem.

I have this :

[
  {
    "date": "2014-04-23 00:00:00",
    "volumetrie": "22458"
  },
  {
    "date": "2014-05-02 00:00:00",
    "volumetrie": "30585"
  },
  {
    "date": "2014-03-27 00:00:00",
    "volumetrie": "49536"
  }
]

And i would like this :

[
  {
    "x": "2014-04-23T22:00:00.000Z",
    "y": 22458
  },
  {
    "x": "2014-05-02T22:00:00.000Z",
    "y": 30585
  },
  {
    "x": "2014-03-27T22:00:00.000Z",
    "y": 49536
  }
]

Do you have any ideas ? Thank you very much for you future answer ;)

Answer 1

Use Array.map:

var arr = [
  {
    "date": "2014-04-23 00:00:00",
    "volumetrie": "22458"
  },
  {
    "date": "2014-05-02 00:00:00",
    "volumetrie": "30585"
  },
  {
    "date": "2014-03-27 00:00:00",
    "volumetrie": "49536"
  }
];

var newArr = arr.map(function(item){
   return {x: item.date, y: item.volumetrie};
});
