+/**
+ * Creates a slice of `array` excluding elements dropped from the beginning.
+ * Elements are dropped until `predicate` returns falsey. The predicate is
+ * bound to `thisArg` and invoked with three arguments; (value, index, array).
+ *
+ * If a property name is provided for `predicate` the created "_.property"
+ * style callback returns the property value of the given element.
+ *
+ * If an object is provided for `predicate` the created "_.matches" style
+ * callback returns `true` for elements that have the properties of the given
+ * object, else `false`.
+ *
+ * @static
+ * @memberOf _
+ * @type Function
+ * @category Array
+ * @param {Array} array The array to query.
+ * @param {Function|Object|string} [predicate=_.identity] The function invoked
+ *  per element.
+ * @param {*} [thisArg] The `this` binding of `predicate`.
+ * @returns {Array} Returns the slice of `array`.
+ * @example
+ *
+ * _.dropWhile([1, 2, 3], function(n) { return n < 3; });
+ * // => [3]
+ *
+ * var users = [
+ *   { 'user': 'barney',  'status': 'busy', 'active': true },
+ *   { 'user': 'fred',    'status': 'busy', 'active': false },
+ *   { 'user': 'pebbles', 'status': 'away', 'active': true }
+ * ];
+ *
+ * // using the "_.property" callback shorthand
+ * _.pluck(_.dropWhile(users, 'active'), 'user');
+ * // => ['fred', 'pebbles']
+ *
+ * // using the "_.matches" callback shorthand
+ * _.pluck(_.dropWhile(users, { 'status': 'busy' }), 'user');
+ * // => ['pebbles']
