|  |  * This method is like `_.curry` except that arguments are applied to `func` | ||
|  |  * in the manner of `_.partialRight` instead of `_.partial`. | ||
|  |  * | ||
|  |  * The `_.curryRight.placeholder` value, which defaults to `_` in monolithic | ||
|  |  * builds, may be used as a placeholder for provided arguments. | ||
|  |  * | ||
|  |  * **Note:** This method doesn't set the "length" property of curried functions. | ||

|  |  * @param {Function} func The function to curry. | ||
|  |  * @param {number} [arity=func.length] The arity of `func`. | ||
|  |  * @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`. | ||
|  |  * @returns {Function} Returns the new curried function. | ||
|  |  * @example | ||
|  |  * | ||
|  |  * var abc = function(a, b, c) { | ||
|  |  *   return [a, b, c]; | ||
|  |  * }; | ||
|  |  * | ||

|  |  * curried(3)(2)(1); | ||

|  |  * curried(1, 2, 3); | ||
|  |  * // => [1, 2, 3]
