I've got an object:

var obj = {
    "Mike": 24,
    "Peter": 23,
    "Simon": 33,
    "Tom": 12,
    "Frank": 31
};

I want to create an array that holds the values of the object. The keys (key names) can be disregarded:

[24, 23, 33, 12, 31]

The order of the values is NOT important!

One solution (obviously) would be do have a function that takes the values and puts them into an array:

var arr = valuesToArray(obj); 

I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?
