# chain-get

## 使用Proxy实现的无报错链式优雅取值方法

## 使用

```bash

npm i chain-get -S

```

```js

import chainGet from 'chain-get';

let person = {age: 12, name: 'huruji', sisters: ['a']}

chainGet(person).age()  // 12

chainGet(person).sisters[0]() // a

chainGet(person).sisters[1]() // undefined

chainGet(person).brothers[1]() // undefined

```

从此告别以下这类代码

```js

if (person && person.sister && persion.sister[0]) {

  const sister = person.sister[0]

}

```
