How to convert a JavaScript object to array

Question

I have this object:

var json = {
  "alex" : [
    {'count' : 1, 'date': 2},
    {'count' : 2, 'date': 2},
  ],
  "alex" : [
    {'count' : 10, 'date': '1'},
    {'count' : 20, 'date': '10'},
  ],
};

How do I convert it to:

var arr = [
  {
    name: 'alex',
    data: [[10,1],[20,2]]
  },
  {
    name: 'bob',
    data: [[10,1],[20,2]]
  }
]

That is not JSON. It is a javascript object literal. And an invalid one at that, as you can't have the same property listed twice. That being said, have you made any effort at all to achieve this? — Mike Brant

var json = {
  "alex" : [
    {'count' : 1, 'date': 2},
    {'count' : 2, 'date': 2},
  ],
  "bob" : [
    {'count' : 10, 'date': '1'},
    {'count' : 20, 'date': '10'},
  ],
};


var res = Object.keys(json).map(function (el) {
  return {
    name: el,
    data: json[el].map(function (e) {
      return [e.count, e.date]    
    })
  }  
})

console.log(res);
