+ * Creates a slice of `array` excluding elements dropped from the beginning.
+ * Elements are dropped until `predicate` returns falsey. The predicate is
+ * invoked with three arguments: (value, index, array).

+ * @memberOf _
+ * @category Array
+ * @param {Array} array The array to query.
+ * @param {Function|Object|string} [predicate=_.identity] The function invoked per iteration.
+ * @returns {Array} Returns the slice of `array`.
+ * @example
+ *
+ * var users = [
+ *   { 'user': 'barney',  'active': false },
+ *   { 'user': 'fred',    'active': false },
+ *   { 'user': 'pebbles', 'active': true }
+ * ];
+ *
+ * _.dropWhile(users, function(o) { return !o.active; });
+ * // => objects for ['pebbles']
+ *
+ * // using the `_.matches` iteratee shorthand
+ * _.dropWhile(users, { 'user': 'barney', 'active': false });
+ * // => objects for ['fred', 'pebbles']
+ *
+ * // using the `_.matchesProperty` iteratee shorthand
+ * _.dropWhile(users, ['active', false]);
+ * // => objects for ['pebbles']
+ *
+ * // using the `_.property` iteratee shorthand
