## Install

```bash
$ npm install noop4 --save
```

## Usage

  Nothing happens and no references are created.

```javascript
var noop = require('noop4');

function example (fn) {
  fn = fn || noop();
  return fn('beep');
}

example();
// nothing happened
```

## Why?

  Sometimes the `noop` method is enriched with methods and properties.
  To ensure a clean usage `noop4` creates a new function each time avoiding previous references.
