/**

 * This method is like `_.uniq` except that it accepts `comparator` which

 * is invoked to compare elements of `array`. The order of result values is

 * determined by the order they occur in the array.The comparator is invoked

 * with two arguments: (arrVal, othVal).

 *

 * @static

 * @memberOf _

 * @since 4.0.0

 * @category Array

 * @param {Array} array The array to inspect.

 * @param {Function} [comparator] The comparator invoked per element.

 * @returns {Array} Returns the new duplicate free array.

 * @example

 *

 * var objects = [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }, { 'x': 1, 'y': 2 }];

 *

 * _.uniqWith(objects, _.isEqual);

 * // => [{ 'x': 1, 'y': 2 }, { 'x': 2, 'y': 1 }]
