## README

# fill-keys

> Fill keys in a destination that are defined on the source. Copies descriptors so properties like `enumerable` will persist. 


## Install

```
$ npm install --save fill-keys
```


## Usage

```js
const fillKeys = require('fill-keys')

fillKeys(destination, source);
//=> missing destination keys in source are copied
```

fill-keys will copy descriptors. It will also copy the `source.prototype` properties onto `destination.prototype` if both `destination` and `source` are functions. 

## API

#### `fillKeys(destination, source)` -> `destination`

#### `destination`

*Required*  
Type: `any`

The destination object where keys from `source` will be added.

#### source
