/**
* 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']
