## Install

Install package:

```bash
npm install defu
```

OR

```bash
yarn add defu
```

## Usage

```js
const options = defu (object, ...defaults)
```

Most left arguments have more perioriry when assigning defaults.

### Arguments

- **object (Object):** The destination object.
- **source (Object):** The source object.

```js
const defu = require('defu')

console.log(defu({ 'a': { 'b': 2 } }, { 'a': { 'b': 1, 'c': 3 } }))
// => { a: { b: 2, c: 3 } }
```

### Remarks

- `object` and `defaults` are not modified
- `null` values are skipped same as [defaults-deep](https://www.npmjs.com/package/defaults-deep). Please use either [omit-deep](http://npmjs.com/package/omit-deep) or [lodash.defaultsdeep](https://www.npmjs.com/package/lodash.defaultsdeep) if you need to to preserve.
- Assignment of `__proto__` and `constructor` keys will be skipped to prevent security issues with object pollution.
