var x = [
    {id: 22, location: 'Vienna'},
    {id: 13, location: 'London'},
    {id: 21, location: 'Paris'}
];

var keyMap = {
  id: 'value',
  location: 'name'
};

var y = x.map(function(obj) {
  return _.mapKeys(obj, function(value, key) {
    return keyMap[key];
  });
});

document.querySelector('#result').innerHTML = JSON.stringify(y, undefined, 2);
