Convert array to object

The extend() method can be used to create objects dynamically from other objects passed in as arguments. In your case, it looks like the objects in the ‘$Array’ field do not have overlapping keys, so you can directly use the array as the arguments to extend. However, you cannot just pass ‘$Array’ to extend(), you need to use the spread operator to indicate that the elements of the array should be treated as the arguments to the function, like so:

{}.extend(...$Array)

The {} part just creates an empty object for us to call extend() on.

There are a few other examples of using the extend() method in the community, like this one.
