 ## Using Iterators for List Attributes
 
 You can also use iterators to create a list of objects based on each item in a list and assign the result as a value to a property of a resource. This is equivalent to using `Array.map` in TypeScript and using [dynamic blocks](/terraform/language/expressions/dynamic-blocks) in a Terraform HCL configuration.
