| * Performs a deep comparison between each element in `collection` and the |
| * source object, returning an array of all elements that have equivalent |
| * property values. |
| * |
| * **Note:** This method supports comparing arrays, booleans, `Date` objects, |
| * numbers, `Object` objects, regexes, and strings. Objects are compared by |
| * their own, not inherited, enumerable properties. For comparing a single |
| * own or inherited property value see `_.matchesProperty`. |

| * @category Collection |
| * @param {Array|Object|string} collection The collection to search. |
| * @param {Object} source The object of property values to match. |
| * @returns {Array} Returns the new filtered array. |
| * @example |
| * |
| * var users = [ |
| * { 'user': 'barney', 'age': 36, 'active': false, 'pets': ['hoppy'] }, |
| * { 'user': 'fred', 'age': 40, 'active': true, 'pets': ['baby puss', 'dino'] } |
| * ]; |
| * |
| * _.pluck(_.where(users, { 'age': 36, 'active': false }), 'user'); |
| * // => ['barney'] |
| * |
| * _.pluck(_.where(users, { 'pets': ['dino'] }), 'user'); |
