.pick

====

A javascript object and array extender that lets you write more elegant code.

## API

### Object.prototype functions

#### .pick(key)

```javascript

var foo = { x: 1, y: 2 };

foo.pick('x');

// yields { x: 1 }

```

#### .into(obj)

```javascript

var foo = { x: 1, y: 2 };

var bar = { z: 34 };

foo.pick('x', 'y')

   .into(bar);

// -> bar = { z: 34, x: 1, y: 2 }

```

#### .mergeWith(array)

```javascript

var foo = { x: 1, y: 2 };

var bar = [ { x: 1 }, { x: 2 }];

foo.pick('y')

   .mergeWith(bar);

// -> bar = [ { x: 1, y: 2 }, { x: 2, y: 2 } ]

```

### Array.prototype functions

#### .pick(key)

```javascript

var foo = [ { y: 1, z: 2 }, { y: 2, z: 3 }];

foo.pick('y')

// yields [ { y: 1 }, { y: 2 } ]

```

#### .into(array)

```javascript

var foo = [ { y: 1, z: 2 }, { y: 2, z: 3 }];

var bar = [ { x: 1 }, { x: 2 }];

foo.pick('y')

   .into(bar)

// -> bar = [ { x: 1 }, { x: 2 }, { y: 1 }, { y: 2 } ]

```

#### .mergeWith(array)

```javascript

var foo = [ { y: 1, z: 2 }, { y: 2, z: 3 }];

var bar = [ { x: 1 }, { x: 2 }];

foo.pick('y')

   .mergeWith(bar)

// -> bar = [ { x: 1, y: 2 }, { x: 2, y: 2 } ]

```

## Notes

This library contains functions that is jacked into Object's and Array's prototype. Take in consideration that this can cause some funny behavior when iterating objects/arrays. Remember, as you always should do, to check `hasOwnProperty` when iterating objects/arrays:

```javascript

for (var key in someObject) {

	if (someObject.hasOwnProperty(key)) {

		// do some stuff

	}

}

```
