[javascript] Iterate over values of object

I want to iterate over all values of a map. I know it's possible to iterate over all keys. But is it possible to iterate directly over the values?

 var map = { key1 : 'value1', key2 : 'value2' }
 for (var key in map) { ...} // iterates over keys

This question is related to javascript dictionary

The answer is

It's not a map. It's simply an Object.

Edit: below code is worse than OP's, as Amit pointed out in comments.

You can "iterate over the values" by actually iterating over the keys with:

var value;
Object.keys(map).forEach(function(key) {
    value = map[key];
