True or False: HashiCorp Configuration Language (HCL) supports user-defined functions.

The statement regarding HashiCorp Configuration Language (HCL) and the presence of user-defined functions is indeed false. HCL is a domain-specific language used by Terraform for defining infrastructure as code. While it provides a rich set of built-in functions to manipulate and work with data types, it does not allow users to define their own functions as part of the language syntax.

This limitation means that users must rely on the provided functions rather than creating custom ones to extend the functionality of HCL. The design of HCL intentionally focuses on simplicity and declarative configuration, which aligns with Terraform's overall philosophy of infrastructure management. As a result, not having user-defined functions helps maintain clarity and reduces complexity within configuration files.

The other choices suggest scenarios that imply user-defined functions exist in some form, either only in specific versions or under certain conditions, but none of these statements accurately reflect HCL's capabilities. Understanding this characteristic of HCL is essential for effectively using Terraform and managing infrastructure without the overhead of custom function definitions.
