# callbag-pluck

Callbag operator that maps to object properties. It intentionally doesn't support default values and expects that path exists (nested property access is not "safe").

## Examples

### Single prop

```js

import fromIter from 'callbag-from-iter'

import forEach from 'callbag-for-each'

import pipe from 'callbag-pipe'

import pluck from 'callbag-pluck'

pipe(

  fromIter([{ name: 'Jurek' }, { name: 'John' }, { name: 'Sherlock' }]),

  pluck('name'),

  forEach(data => {

    // will log 'Jurek', 'John', 'Sherlock'

    console.log(data)

  }),

)

```

### Multiple nested properties

```js

import fromIter from 'callbag-from-iter'

import forEach from 'callbag-for-each'

import pipe from 'callbag-pipe'

import pluck from 'callbag-pluck'

pipe(

  fromIter([

    { some: { nested: { path: 'Apple' } } },

    { some: { nested: { path: 'Banana' } } },

    { some: { nested: { path: 'Orange' } } },

  ]),

  pluck(['some', 'nested', 'path']),

  forEach(data => {

    // will log 'Apple', 'Banana', 'Orange'

    console.log(data)

  }),

)

```
