# ArrayRange

Build an array out of a range of numbers or using our range syntax: {start}..{end} or using the from and to arguments

You can also build negative ranges

```
 arrayRange( "1..5" )
 arrayRange( "-10..5" )
 arrayRange( 1, 500 )
 
```

## Method Signature

```
ArrayRange(from=[any], to=[numeric])
```

### Arguments

| Argument | Type      | Required | Description                                                                 | Default |
| -------- | --------- | -------- | --------------------------------------------------------------------------- | ------- |
| `from`   | `any`     | `false`  | The initial index, defaults to 1 or you can use the {start}..{end} notation | `1`     |
| `to`     | `numeric` | `false`  | The last index item, or defaults to the from value                          |         |

## Examples

### Create an array of sequential numbers using the string syntax.

[Run Example](https://try.boxlang.io/?code=eJxLLCpSsFVILCpKrAxKzEtP1VBQMtLTM1VS0LTmKi%2FKLEn1Ly0pKC0BCodkZBZDFCpkJBYrKCmoQXg%2BqXkaIJaCJlBESSE1JzU3Na%2BkWA9sBACINxyk)

```java
arr = arrayRange( "2..5" );
writeOutput( "This array has " & arrayLen( arr ) & " elements." );

```

Result: This array has 4 elements.
