I’ve been using PowerShell for a long while now using Hashtables, OrderedDictionary, and other types of data types in PowerShell, but I never paid attention to how powerful those are. And I don’t mean your general knowledge about hashtables that is already covered by Kevin Marquette in his article Everything you wanted to know about Hashtables or my article PowerShell – Few tricks about HashTables and Arrays I wish I knew when I started. Let’s find out, how Powerful they are, shall we?
I’ve been working with PowerShell for a while now and like with most things I do I’ve learned it by doing and not by reading. I had a job to do, and since I don’t like doing things over and over, I thought it’s time to learn and do it in PowerShell. Problem with that approach is that you take bits and pieces from PowerShell scripts online that sometimes do the job but not necessarily pay attention to details. And it’s fine. I’ve learned a lot from reading someone else’s work, and I learn something new every day. Hopefully, it will be useful to you to some extent.
