Article summary

Looping over the same series of statements can be useful for both visualization and removing repetitive statements in a plan. That's where the Loop Block comes in.

Loop Blocks run the set of statements in the block while enumerating over a list. The List can be a variable, a function, or a literal expression.

For example, we can create a directory exists for each service in a variable called @ServiceNames. This variable could be defined elsewhere in our plan, or externally as a configuration variable.

Looping and Numbers

With the built-in @Range function, you can loop over numbers just as easily as you might with a c-style "for" loop.
