create []array dynamically in Javascript

Question

Probably this will be a real stupid question to ask but im new in javascript and stuck with dynamic creation of array like in below format:

items = [{
    "Date": "2012-01-21T23:45:10.280Z",
    "Value": 7
}, {
    "Date": "2012-01-26T23:45:10.280Z",
    "Value": 10
}, {
    "Date": "2012-05-30T23:45:10.280Z",
    "Value": 16
}];

Please guide me how do i create above array dynamically using javascript syntax.

Thanks in advance!

Dynamically from what? Current answers are as static as your array literal. — Bergi

var items = []; for(i in d.date) { var arr = i.split("-"); var Item = new function(){ this.Date = arr[0]; this.Value = arr[1]; } items.push(Item);} — Milan Mendpara

var items = []; // initialize array
items.push({ // add 1st item
  "Date": "2012-01-21T23:45:10.280Z",
  "Value": 7
});
items.push({ // add 2nd item
  "Date": "2012-01-26T23:45:10.280Z",
  "Value": 10
});
items.push({ // add 3rd item
  "Date": "2012-05-30T23:45:10.280Z",
  "Value": 16
});

And to view it:

console.log(JSON.stringify(items));

Why do you use JSON.stringify for the log?

@Cerbrus: Just a quick and dirty way to visualize the data's there. You could console.log(items) but then you're having to use the debugger to expand out the object and each element in the array to confirm it's been populated.

Do you mean like this:

items = [];

items.push({
    "Date": "2012-01-21T23:45:10.280Z",
    "Value": 7
});
items.push({
    "Date": "2012-01-26T23:45:10.280Z",
    "Value": 10
});
items.push({
    "Date": "2012-05-30T23:45:10.280Z",
    "Value": 16
});
