Is it possible to have a jagged array in JavaScript?
Here is the format of the data I want to store in a jagged array:
(key)(value1, value2, value3)
Can I put this in a jagged array?

Yes, you can create that type of array using object or array literal grammar, or object/array methods.
An array of arrays:
// Using array literal grammar
var arr = [[value1, value2, value3], [value1, value2]]
// Creating and pushing to an array
var arr = [];
arr.push([value1, value2, value3]);
An object of arrays:
// Using object literal grammar
var obj = { "key": [value1, value2, value3], "key2": [value1, value2] }
// Creating object properties using bracket or dot notation
var obj = {};
obj.key = [value1, value2, value3];
obj["key2"] = [value1, value2];

okay, so using your "Creating object properties using bracket or dot notation" example i could get at a certain value in the following alert?: alert(obj["key2"][])

@William: yes,
alert(obj["key2"][0]) would alert the value of value1, alert(obj["key2"][1]) would alert the value of value2.
