var users = {  'fred':    { 'user': 'fred',    'age': 40 },  'pebbles': { 'user': 'pebbles', 'age': 1 }};

_.mapValues(users, function(o) { return o.age; });
// => { 'fred': 40, 'pebbles': 1 } (iteration order is not guaranteed) 

// The `_.property` iteratee shorthand.
_.mapValues(users, 'age');

lodash map

Comment

Creates an array of values by running each element in collection thru iteratee. The iteratee is invoked with three arguments:
(value, index|key, collection).

function square(n) {
  return n * n;
}
 
_.map([4, 8], square);
// => [16, 64]
 
_.map({ 'a': 4, 'b': 8 }, square);
// => [16, 64] (iteration order is not guaranteed)
 
var users = [
  { 'user': 'barney' },
  { 'user': 'fred' }
];
 
// The `_.property` iteratee shorthand.
_.map(users, 'user');
// => ['barney', 'fred']
