I have a two-dimensional array that is formatted as followed:
[["a",1], ["b",2]]
I want to change its formatting to this:
{"a":1,"b":2}
How can I do this? Sorry if it is an easy/stupid question.

I will assume you're sure that the same key won't appear twice (i.e., there won't be two inner arrays with "a"):
var inputArray = [["a",1], ["b",2]],
outputObject = {},
i;
for (i = 0; i < inputArray.length; i++)
outputObject[inputArray[i][0]] = inputArray[i][1];
If that's not enough jQuery for you then I guess you can use $.each() instead of a for loop, etc., but in my opinion a plain for loop is fine for this sort of thing.

var arr = [["a",1], ["b",2]], obj = {}, i;
for (i = 0; i < arr.length; i++) {
obj[arr[i][0]] = arr[i][1];
}

This is pretty easy:
var myList = {};
for( var i in myArray ) {
myList[myArray[i][0]] = myArray[i][1];
}

var result = {};
$.each([["a",1], ["b", 2]], function(){result[this[0]] = this[1]})

You can iterate through the multidimensional array, assigning the inner arrays first index as the property and the second as the value.
var arr = [["a",1], ["b",2]];
var obj = {};
for(var i = 0; i < arr.length; i++){
obj[arr[i][0]] = arr[i][1];
}

Assuming the key won't appear twice:
var o = {};
[["a",1], ["b",2]].forEach(function(value) {o[value[0]] = value[1];});
