divideBy

DataWeave 2.1 is compatible with Mule 4.1. Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule will reach its End of Life on November 2, 2022, when Extended Support ends.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

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

Breaks up a list (array) into sub-lists (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

Name Description

items

Items in the input array.

amount

The number of elements allowed per sub-array.

Example

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