> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

## divideBy(Array<T>, Number): Array<Array<T>>

Breaks up an array into sub-arrays that contain the specified number of elements.

When there are fewer elements in the input array than the specified number, the function fills the
sub-array with those elements. When there are more elements, the function fills as many sub-arrays
needed with the extra elements.

### Parameters

<table><colgroup><col> <col></colgroup><thead><tr><th>Name</th><th>Description</th></tr></thead><tbody><tr><td><p><code>items</code></p></td><td><p>Items in the input array.</p></td></tr><tr><td><p><code>amount</code></p></td><td><p>The number of elements allowed per sub-array.</p></td></tr></tbody></table>

### Example

This example breaks up arrays into sub-arrays based on the specified `amount`.
