Adding data to a Javascript array of arrays

Question

I'm trying to add data to an array, and getting a weird result.

var arr = [];

var obj1 = { data: ["a","b"]};
var obj2 = { data: ["c","d"]};

arr.push(obj1);
arr[0].data.push(obj2.data);

console.log(arr[0].data);

// 1) what i want: [ ["a", "b"], ["c", "d"] ]
// 2) what i get:  ["a", "b", ["c", "d"] ]

Any idea how can I set it up so that I get the data formatted like: [["a","b"],["c","d"]]? Here's a fiddle for it: http://jsfiddle.net/oakley808/UCQ65/

Try this:

var arr = [];

var obj1 = { data: ["a","b"]};
var obj2 = { data: ["c","d"]};

arr.push(obj1.data);
arr.push(obj2.data);

console.log(arr);
