[](http://github.com/badges/stability-badges)
Tiny module to create a new dense array with the specified range.
```js
var range = require('array-range')
range(3) // -> [ 0, 1, 2 ]
range(1, 4) // -> [ 1, 2, 3 ]
```
Mainly useful for functional programming. ES6 examples:
```js
var array = require('array-range')
array(5).map( x => x*x )
// -> [ 0, 1, 4, 9, 16 ]
array(2, 10).filter( x => x%2===0 )
// -> [ 2, 4, 6, 8 ]
```
It can also be useful for creating a fixed size dense array. Cleaner than `apply` and does not create an intermediate array:
```js
array(5)
//vs.
Array.apply(null, new Array(5))
```
## Usage
[](https://nodei.co/npm/array-range/)
#### `array(start, end)`
Creates a new dense array with a length of `end-start` elements. `start` is inclusive, `end` is exclusive. Negative values also work, e.g. `range(-10, 10)`
#### `array(len)`
Creates a new dense array with `len` number of elements, from zero to `len-1`.
If `len` is unspecified, it defaults to zero (empty array).
