Summary

  • 3 minutes

In this module, you learned to use scripting constructs such as the ForEach construct to process all objects in an array and the If..Else and Switch constructs to make decisions in your scripts. 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.

  • PowerShell 7 adds the -Parallel parameter to the ForEach-Object cmdlet, allowing 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.

  • Other less common looping constructs include Do..While, Do..Until, and While.

  • Use Break and Continue to modify loop behavior. Continue ends processing for the current iteration. Break completely stops the loop.
