|
* 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.
