**描述：**

这个函数类似[`_.partial`](https://lodash.com/docs/4.17.10#partial)，除了预设参数被附加到接受参数的后面。

这个`_.partialRight.placeholder`的值，默认是以`_`作为附加部分参数的占位符。

> **注意:**这个方法不会设置 "length" 到函数上。

**开始版本：**1.0.0

**参数：**

* `func (Function)`: 需要预设的函数。
* `[partials] (...*)`: 预设的参数。

**返回值：**

* `(Function)`:返回预设参数的函数。

**例子：**

```javascript
var greet = function(greeting, name) {
  return greeting + ' ' + name;
};

var greetFred = _.partialRight(greet, 'fred');
greetFred('hi');
// => 'hi fred'

// 使用了占位符。
var sayHelloTo = _.partialRight(greet, 'hello', _);
sayHelloTo('fred');
// => 'hello fred'
```
