Summary
In this module, you learned to use scripting constructs such as the ForEach construct to process all of the objects in an array and the If..Else and Switch constructs to make decisions in your scripts. The following are the key takeaways:
Use the ForEach-Object cmdlet to process the data in the pipeline. When you store data in an array, the ForEach construct allows you to process each item in the array.
In PowerShell 7, the -Parallel parameter was added to the ForEach-Object cmdlet. This allows the pipeline to process multiple objects simultaneously.
Use the If construct in Windows PowerShell to make decisions.
The Switch construct is similar to an If construct that has multiple ElseIf sections.
The For construct performs a series of loops similar to a ForEach construct. However, when using the For construct, you must define how many loops occur, which is useful when you want an action to be performed a specific number of times.
There are other less common looping constructs that you can use. These are Do..While, Do..Until, and While.
Break and Continue are two commands that you can use to modify the default behavior of a loop. Continue ends the processing for the current iteration of the loop. Break completely stops the loop processing.
