In this part of the chapter, we will take a look at the language constructs of PowerShell, to control the flow of the scripts. We will make use of operators and conditions, but will also look at different types of loops. You have to learn these constructs wisely and be aware of all of these upcoming keywords. Everything in this topic comprises a basic tool set to create powerful and efficient scripts, which will save you a lot of time. This is why you are actually learning PowerShell.

Because PowerShell works with the underlying .NET Framework, you will recognize that it has nearly the same complete feature set as, for example, the .NET-based programming language C#. In fact, you can always make use of any features and possibilities in C# by invoking C# code. We will illustrate these kinds of features at the end of the book. Because of the importance of the upcoming language constructs, you should test them on your own. As we initially explained, you can work with the demo scripts, and try to extend them.
