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

* @param {Function} func The function to partially apply arguments to. |
|
* @param {...*} [partials] The arguments to be partially applied. |

|

* greetFred('hi'); |

* // => 'hi fred' |

|
* // Partially applied with placeholders. |
|
* var sayHelloTo = _.partialRight(greet, 'hello', _); |
