+/**
+ * This method is like `_.uniq` except that it accepts `iteratee` which is
+ * invoked for each element in `array` to generate the criterion by which
+ * uniqueness is computed. The iteratee is invoked with one argument: (value).

+ * @static
+ * @memberOf _
+ * @since 4.0.0

+ * @param {Array} array The array to inspect.
+ * @param {Array|Function|Object|string} [iteratee=_.identity]
+ *  The iteratee invoked per element.
+ * @returns {Array} Returns the new duplicate free array.
+ * @example
+ *
+ * _.uniqBy([2.1, 1.2, 2.3], Math.floor);
+ * // => [2.1, 1.2]
+ *
+ * // The `_.property` iteratee shorthand.
+ * _.uniqBy([{ 'x': 1 }, { 'x': 2 }, { 'x': 1 }], 'x');
