Install with [npm](https://www.npmjs.com/):
```sh
$ npm install --save object.map
```
## Usage
```js
var mapValues = require('object.map');
var result = mapValues({a: 'a', b: 'b'}, function(val, key, obj) {
return val + val;
});
console.log(result);
//=> {a: 'aa', b: 'bb'}
```
Optionally specify a `thisArg` as the last argument:
```js
var result = mapValues({a: 'b'}, function(val, key, obj) {
return this.foo;
}, {foo: 'bar'});
console.log(result);
//=> {a: 'bar'}
