| * The opposite of `_.filter`; this method returns the elements of `collection` |
| * that `predicate` does **not** return truthy for. |
| * |
| * @static |
| * @memberOf _ |
| * @category Collection |
| * @param {Array|Object|string} collection The collection to iterate over. |
| * @param {Function|Object|string} [predicate=_.identity] The function invoked |
| * per iteration. |
| * @param {*} [thisArg] The `this` binding of `predicate`. |
| * @returns {Array} Returns the new filtered array. |
| * @example |
| * |
| * _.reject([1, 2, 3, 4], function(n) { |
| * return n % 2 == 0; |
| * }); |
| * // => [1, 3] |
| * |
| * var users = [ |
| * { 'user': 'barney', 'age': 36, 'active': false }, |
| * { 'user': 'fred', 'age': 40, 'active': true } |
| * ]; |
| * |
| * // using the `_.matches` callback shorthand |
| * _.pluck(_.reject(users, { 'age': 40, 'active': true }), 'user'); |
| * // => ['barney'] |
| * |
| * // using the `_.matchesProperty` callback shorthand |
| * _.pluck(_.reject(users, 'active', false), 'user'); |
| * // => ['fred'] |
| * |
| * // using the `_.property` callback shorthand |
| * _.pluck(_.reject(users, 'active'), 'user'); |
| * // => ['barney'] |
