# ArraySlice

Extracts a sub array from an existing array.

## Method Signature

```
ArraySlice(array=[array], start=[integer], length=[integer])
```

### Arguments

| Argument | Type      | Required | Description                                                                                            | Default |
| -------- | --------- | -------- | ------------------------------------------------------------------------------------------------------ | ------- |
| `array`  | `array`   | `true`   | The array to slice.                                                                                    |         |
| `start`  | `integer` | `true`   | The position to start the slice from. Negative values count from the end of the array.                 | `1`     |
| `length` | `integer` | `false`  | The number of elements to return. 0 (default) returns all elements from start to the end of the array. | `0`     |

## Examples

### Simple arraySlice Example

[Run Example](https://try.boxlang.io/?code=eJxLLCpKrFSwVYhW4OI01OHiNAJiYyA2AWJTIDYDYnMgtuCKtebKSy13hKpPBNHBOZnJqRoQto6CkY6CsYKmNVd5UWZJakppboGGAlwDUBgA%2Baoa%2Bw%3D%3D)

```java
array = [ 
	1,
	2,
	3,
	4,
	5,
	6,
	7,
	8
];
newArray = arraySlice( array, 2, 3 );
writedump( newArray );

```

Result: \[2,3,4]

### arraySlice with no length specified

array = [ 
	1,
	2,
	3,
	4,
	5,
	6,
	7,
	8
];
newArray = arraySlice( array, 4 );
writedump( newArray );

```

Result: \[4,5,6,7,8]

### arraySlice using a negative offset

writedump( newArray );

```

Result: \[4,5,6]

### Slice an array using member function

Calling the slice member function on an array.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://boxlang.ortusbooks.com/boxlang-language/reference/built-in-functions/array/arrayslice.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
