How to create individual objects and list them in an array using javascript?

Question

My current array is not creating individual objects as I would like it to. My data is in the following format:

["1434100866", "599.0", "1434100870", "349.0", "1434100863", "233.0", "1434100849", "269.0", "1434100857", "682.0", "1434100862", "248.0", "1434100865", "342.0", "1434100848", "960.0", "1434100853", "270.0", "1434100850", "253.0"]

I would like my data to be in the following format:

[[item1, item2],[item1, item2],[item1, item2], ...];

Here's my code:

        var dataArray = new Array();
        @foreach (var record in Model)
        {
            @:dataArray.push("@record.date", "@record.rate");
        }        
        console.log(dataArray);

Well it does because I'm using mvc 4 view for this example. I put it the C# category because I figured maybe it was an issue with razor script syntax, etc. — Fullmetal_Alchemist_Fan, Jun 29 '15 at 21:41

You want to push a new array, not new values. Do this:

var dataArray = new Array();
@foreach (var record in Model)
{
    @:dataArray.push(["@record.date", "@record.rate"]);
}        
console.log(dataArray);

Yeah, but this is how the data comes out now: dataArray.push(["1434100866", "599.0"]); dataArray.push(["1434100870", "349.0"]); dataArray.push(["1434100863", "233.0"]); dataArray.push(["1434100849", "269.0"]); dataArray.push(["1434100857", "682.0"]); dataArray.push(["1434100862", "248.0"]); dataArray.push(["1434100865", "342.0"]); dataArray.push(["1434100848", "960.0"]); dataArray.push(["1434100853", "270.0"]); dataArray.push(["1434100850", "253.0"]); – Fullmetal_Alchemist_Fan Jun 29 '15 at 21:47
No. This is correct. It turned out that my datatypes were incorrect. – Fullmetal_Alchemist_Fan Jun 29 '15 at 22:14

var a=["1434100866", "599.0", "1434100870", "349.0", "1434100863", "233.0", "1434100849", "269.0", "1434100857", "682.0", "1434100862", "248.0", "1434100865", "342.0", "1434100848", "960.0", "1434100853", "270.0", "1434100850", "253.0"];
var b = a.reduce(function (res, el, i) {
    if (i % 2) {
        res[res.length - 1].push(el);
    } else {
        res.push([el]);
    }
    return res;
}, []);
 document.getElementById('out').innerHTML = JSON.stringify(b, null, 4);
