# pluck

#### signature: `pluck(properties: ...args): Observable`

## 값을 발생시킬 프로퍼티를 선택합니다

### 예시

**예시1: 객체 프로퍼티 뽑아내기**

( [StackBlitz](https://stackblitz.com/edit/typescript-jkda4e?file=index.ts\&devtoolsheight=100) | [jsBin](http://jsbin.com/zokaxiwahe/1/edit?js,console) | [jsFiddle](https://jsfiddle.net/btroncone/58v9xq0f/) )

```javascript
// RxJS v6+
import { from } from 'rxjs';
import { pluck } from 'rxjs/operators';

const source = from([{ name: 'Joe', age: 30 }, { name: 'Sarah', age: 35 }]);
//names만 가져옵니다
const example = source.pipe(pluck('name'));
//결과: "Joe", "Sarah"
const subscribe = example.subscribe(val => console.log(val));
```

**예시 2: nested 프로퍼티 뽑아내기**

( [StackBlitz](https://stackblitz.com/edit/typescript-rinjzk?file=index.ts\&devtoolsheight=100) | [jsBin](http://jsbin.com/joqesidugu/1/edit?js,console) | [jsFiddle](https://jsfiddle.net/btroncone/n592m597/) )

```javascript
// RxJS v6+
import { from } from 'rxjs';
import { pluck } from 'rxjs/operators';

const source = from([
  { name: 'Joe', age: 30, job: { title: 'Developer', language: 'JavaScript' } },
  //job 값이 없으면 undefined를 반환할 것입니다
  { name: 'Sarah', age: 35 }
]);
//job 안의 title프로퍼티를 뽑아냅니다
const example = source.pipe(pluck('job', 'title'));
//결과: "Developer" , undefined
const subscribe = example.subscribe(val => console.log(val));
```
