function types when it comes to code encapsulation. In most cases, a defined type is best, but there are some situations where a function is more appropriate.
Use a defined type when:
Use a function when:
Additionally, functions are useful for transforming data, such as combining data from multiple sources or converting data from one format to another. Functions can also help to encapsulate complex or repetitive code, making your Puppet code easier to read and maintain.
Abstraction can also lead to entanglement, where different parts of the code become tightly coupled and difficult to modify or maintain.
