1So you want to convert an array into an array(of the same length) which has a subarray of the same values? Unless you want to add objects inside your array, I don't see any point in doing that. But if you want to do, use the map function over the arr and return [data] (assuming data is the function parameter)shash7– shash72014-02-13 16:37:00 +00:00Commented Feb 13, 2014 at 16:37

In JavaScript the Array is this: ["michael", "jason"]
This is an Object: {0: "michael", 1: "jason"}
To convert Array as you wrote you can use script like this:
var a = ["michael", "jason"];
for (var i=0; i<a.length; i++) {
a[i] = [a[i]];
}
To convert Object as you wrote you can use script like this:
var obj = {0: "michael", 1: "jason"};
for (var i in obj) { // here is a difference - using `in` keyword
obj[i] = [obj[i]];
}
Here is a working fiddle.
UPDATE:
For modern browsers (IE9+, FF1.5+) you can use map method of Array object:
var a = ["michael", "jason"];
a = a.map(function(item) {
return [item];
});
