Loops over every item matching the path you give and applies one or more transformers to each item on its own. Use this when your data contains a repeating list, such as the products in an order or the posts in a feed, and you want to run the same set of changes on each item individually instead of on the whole list at once. The transformers you choose run in order against each matched item, so paths and placeholders inside them are read relative to that item.

Sample data

This feature is a wrapper: it does not change data on its own, it runs the transformers you place inside it once per matched item. The example below loops over every post in http.posts and, for each post, adds a userName taken from a matching user.
