Summary
The functions in PowerShell are powerful and extremely useful to create flexible, reusable code. Parameters, including switch parameters, allow you to tailor the execution of a function to meet your needs. PowerShell functions behave differently from functions in many other languages, potentially outputting multiple objects of different types and at different times.
In the next chapter, we will look at PowerShell modules, a feature added in PowerShell 2.0 to help gather functions and scripts into libraries.
