Get object values without looping [duplicate]

Question

I have following object:

var input = {
  'foo': 2,
  'bar': 6,
  'baz': 4
};

Is it possible to get values from this object without looping it ?

It is possible to use jQuery.

Expected result:

var output = [2, 6, 4];

Answer 1

var arr = $.map(input,function(v){
 return v;
});

Answer 2

This is simply not possible without a loop. There's no Object.values() method (yet) to complement Object.keys().

Until then you're basically "stuck" with the below construct:

var values = [];

for (var k in input) {
  if (input.hasOwnProperty(k)) {
    values.push(input[k]);
  }
}

Or, in modern browsers (but of course still using a loop and an anonymous function call):

var values = Object.getOwnPropertyNames(input).map(function(key) {
    return input[key];
});
