Working with Script Blocks

Abstract

The PowerShell programming language is very dynamic. Until now, I have focused on its abilities to manipulate objects of any kind. In this chapter, we will explore my favorite language feature: script blocks. Blocks help craft elegant code not only when manipulating collections of objects but in many other situations. Most importantly, script blocks allow us to encapsulate pieces of code and delay their execution. Script blocks are containers holding pieces of code that do not have to be assigned a formal name. We can create them dynamically in the middle of any script operation, and, of course, we can execute them multiple times, passing different parameters.
