| /** |
| * The opposite of `_.filter` this method returns the elements of a |
| * collection that the callback does **not** return truey for. |
| * |
| * If a property name is provided for `callback` the created "_.pluck" style |
| * callback will return the property value of the given element. |
| * |
| * If an object is provided for `callback` the created "_.where" style callback |
| * will return `true` for elements that have the properties of the given object, |
| * else `false`. |
| * |
| * @static |
| * @memberOf _ |
| * @category Collections |
| * @param {Array|Object|string} collection The collection to iterate over. |
| * @param {Function|Object|string} [callback=identity] The function called |
| * per iteration. If a property name or object is provided it will be used |
| * to create a "_.pluck" or "_.where" style callback, respectively. |
| * @param {*} [thisArg] The `this` binding of `callback`. |
| * @returns {Array} Returns a new array of elements that failed the callback check. |
| * @example |
| * |
| * var odds = _.reject([1, 2, 3, 4, 5, 6], function(num) { return num % 2 == 0; }); |
| * // => [1, 3, 5] |
| * |
| * var characters = [ |
| * { 'name': 'barney', 'age': 36, 'blocked': false }, |
| * { 'name': 'fred', 'age': 40, 'blocked': true } |
| * ]; |
| * |
| * // using "_.pluck" callback shorthand |
| * _.reject(characters, 'blocked'); |
| * // => [{ 'name': 'barney', 'age': 36, 'blocked': false }] |
| * |
| * // using "_.where" callback shorthand |
| * _.reject(characters, { 'age': 36 }); |
| * // => [{ 'name': 'fred', 'age': 40, 'blocked': true }] |
