> Coalesce for JavaScript. Returns the first value that is not undefined or null.

## Install

Install with [npm](https://www.npmjs.com/):

```sh
$ npm install --save koalas
```

## Usage

```js
var koalas = require('koalas');
```

## API

### [koalas](index.js#L27)

Coalesce function to find the first valid value. A valid value is one that is not undefined, not null and not NaN (not a number). If no values are valid, then the last argument is returned.

**Params**

* `arguments` **{Mixed}**: Pass in any amount of arguments.
* `returns` **{Mixed}**: First valid value.

**Example**

```js
console.log(koalas(undefined, null, NaN, 'a', 'b'));
//=> 'a'

console.log(koalas(undefined, null, NaN, {a: 'b'}, 'b'));
//=> {a: 'b'}

console.log(koalas(undefined, null, NaN, ['a', 'b', 'c'], {a: 'b'}, 'b'));
//=> ['a', 'b', 'c']

console.log(koalas(undefined, NaN, null));
//=> null
```
