Combine arrays into an object?

I have the following arrays:

dates = ['2013-06-01', '2013-07-01', '2013-08-01', '2013-09-01', '2013-10-01', '2013-11-01']
values = [20, 10, 5, 5, 20, 25]

What I need to do is merge them into this format:

data: [
  { date: '2013-06-01', value: 20 },
  { date: '2013-07-01', value: 10 },
  { date: '2013-08-01', value: 5 },
  { date: '2013-09-01', value: 5 },
  { date: '2013-10-01', value: 20 },
  { date: '2013-11-01', value: 25 }
]

hmm. I'm sure you already thought of this. using jquery, apologize if you don't use this.

 data = jQuery.map(dates,function(v,i){
      return {'date': i, 'value': values[i]}
 }

var data = {
  data: dates.map(function(x, i) {
    return { date: x, value: values[i] };
  })
};

Array.prototype.map is ECMAScript 5th Edition and doesn't work in < IE9. For older browsers us this polyfill

If jQuery is an option, you can try this:

Assuming they're always the same length:

var data = [];
for (var i = 0; i < dates.length; i++) {
    var obj = {}
    obj.date = dates[i];
    obj.value = values[i];
    data.push(obj);
}
