Summary

In this chapter, we have seen the main building blocks of PowerShell as a language. We have demonstrated how similar functionality can be implemented using a function, a script, and a module. An emphasis was placed on how PowerShell's use of an object-oriented pipeline gives tremendous advantages in terms of flexibility without re-implementing common features such as sorting and filtering in each function.

PowerShell provides an innovative programming and scripting experience. The next chapter will highlight various ways that the PowerShell language functions differently from other programming languages.
