Map a function over the values of an Object to produce a new Object with the same keys.

The API is modelled after the native [Array#map](https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/map) method.

## Installation

```bash

$ npm install --save object-map

```

## Example

```js

var objectMap = require('object-map');

var target = {

  foo: 1,

  bar: 2

};

var result = objectMap(target, function(value) {

  return value * value;

});

// => {foo: 1, bar: 4}

```

## API

`objectMap(target, callback[, thisArg])`

- `target` an object who's properties are iterated using `hasOwnProperty`

- `callback` a function producing a value of the new Object, taking three arguments:

  - `currentValue` the value currently associated with the key

  - `key` the current key

  - `object` the original object passed to `objectMap`

- `thisArg` Optional. Value to use as `this` when executing `callback`.
