What type of function is a!forEach() in Appian?

The function a!forEach() in Appian is categorized as an iterative function. This function is specifically designed to iterate over a collection of items, allowing developers to apply a specified action or transformation to each element within that collection. Its primary use is to handle lists effectively within the Appian environment, which is essential for processes that require repeating operations on all items in a set, such as aggregating data or generating a list of user-facing outputs.

By using a!forEach(), developers can create dynamic and efficient applications since they can seamlessly perform actions on multiple items without needing to write extensive loops manually. This function simplifies coding by providing a built-in mechanism to manage iterations cleanly and expressively, promoting both readability and maintainability of the code in Appian applications.

The other available options do not accurately describe the nature of a!forEach(). Conditional functions are focused on decision-making based on specific criteria, data-saving functions are related to persisting information, and user interfacing functions are designed to manage user interface components. None of these relate to the iterative capability that a!forEach() provides in handling collections.
