Answer 1

There's no built-in way to do this anywhere. The following does what you suggest, and may be "shortened" into more clever functional-programming versions depending on your library, but they'll all have the same efficiency.

function valuesToArray(obj) {
    var result = [];
    for (var key in obj) {
       if (obj.hasOwnProperty(key)) {
           result.push(obj[key]);
       }
    }
    return result;
}

Answer 2

Using the Underscore lib try:

function valuesToArray(o) {
    return _.pairs(o);
}

var obj = {
    "Mike": 24,
    "Peter": 23
    //...
    },
    result = valuesToArray(obj);

Then the result is [ ["Mike", 24], ["Peter", 23] ];

Answer 3

Using bob.js this can be done pretty simply:

function valuesToArray(obj) {
    return bob.collections.extensions.toArray.call(obj);
}
