## README

# assure-array

Wraps a value in an array if it isn't already one. Returns an empty array for `null` and `undefined`.

A typical usecase for this: when you have an option that accepts multiple values as an array, but you want to make the use of an array literal optional when there's only a single value to specify.

## Usage

Some examples:

```javascript
var assureArray = require("assure-array");

assureArray("hello world");      // ["hello world!"]
assureArray(["hello", "world"]); // ["hello", "world"]
assureArray(null);               // []
assureArray([true]);             // [true]
```

## API

### assureArray(value)

Ensures that the provided `value` is returned as an array.

* If `value` is an array already, this returns the array unchanged.
* If `value` is `null` or `undefined`, this returns an empty array.
* If `value` is any other kind of value, this returns a new array containing just that one value.
