# assign

> Reference for the assign workflow task, which copies enumerable properties from a source object to a target object.

## Task purpose

The `assign` task copies all enumerable properties from a source object to a target object. It returns a modified target object with properties and values pushed from the source object. The target object is the first parameter and is also used as the return value (`targetObject`).

## Potential use case

Suppose you have an ordered list of emails in a collection and you want to assign them into a numbered list. The target object and the source object will be given the numerical assignments in the final list.

## Task properties

| Incoming  | Type   | Description                                                    |
| --------- | ------ | -------------------------------------------------------------- |
| `target`  | Object | Required. The target object to apply the source properties to. |
| `sourceN` | Object | Required. The source object containing the properties to copy. |

| Outgoing       | Type   | Description        |
| -------------- | ------ | ------------------ |
| `targetObject` | Object | The target object. |

## Configure the task

In the example below:

* Property `a` has been assigned the value `1` in the `target` object.
* Property `b` has been assigned the value `2` in the `sourceN` object.
* The source object `"b": 2` is copied to the target object, and `targetObject` returns the combined result `"a": 1, "b": 2`.
