JavaScript Multidimensional arrays - column to row

Question

Is it possible to turn a column of a multidimensional array to row using JavaScript (maybe Jquery)? (without looping through it)

so in the example below:

 var data = new Array();

 //data is a 2D array
 data.push([name1,id1,major1]);
 data.push([name2,id2,major2]);
 data.push([name3,id3,major3]);
 //etc..

Is possible to get a list of IDs from data without looping? thanks

No, it is not possible to construct an array of IDs without looping.

In case you were wondering, you'd do it like this:

var ids = [];
for(var i = 0; i < data.length; i++) 
    ids.push(data[i][1]);

For better structural integrity, I'd suggest using an array of objects, like so:

data.push({"name": name1, "id": id1, "major":major1});
data.push({"name": name2, "id": id2, "major":major2});
data.push({"name": name3, "id": id3, "major":major3});

Then iterate through it like so:

var ids = [];
for(var i = 0; i < data.length; i++) 
    ids.push(data[i].id);
