- Learn how to work with PowerShell Functions. In this episode of Learn PowerShell I dive into what makes up a PowerShell Function. Discover the difference between an advanced and standard PowerShell function. I also tackle the question of why you might write a PowerShell Function vs PowerShell Script. Go beyond theory - this episode uses real life fully functional PowerShell Functions to explore how functions are made and how they operate.

I wish I could like this many more times, I have spent weeks reading and trying to understand functions. This 30ish minute video has shot my confidence and understanding of functions through the roof and I look forward to building my own functions now. THANK YOU for making this video, it's been a tremendous help, so much more to discover on my own but I have learn enough here to feel confident moving forward.
Edit:
One month later and I have grown to making my own modules and even manifests. Been sharing the tools I've made and this all around has been so useful
No way! I started learning ps a week ago and now you continue the series :D
Thank you very much for your awesome work!
Amazing tutorial and the best I've see about PowerShell functions. Thank you so much!
Like Moss from the IT-Crowd would say, "This is INSANELY brilliant!"
Went on and donated since this is one of the best courses on coding. The info is available everywhere but the structure and the practical examples makes the difference.
Many thanks. You are the first person that donated, and it was much appreciated. I never got around to linking the account, and as a result, you were refunded. But I appreciate the gesture and thanks for being the first person to donate. It means a lot.
Amazing explanation. Way better than Microsoft's documentation :-D
Learning a lot with these series! thanks!
Great presentation. Thank you for your efforts!
As a DevOps engineer who uses PS alot, I learnt a few things and my knowledge was solidified further after watching this. Nice video! Subscribed.
Super helpful and just what I needed; thank you for the completeness of this video!
Very nice. Great video.
Thank you very much!! Really Helpful!!
Thanks for bringing powershell functions. If possible please keep on bringing new videos. It's very heplful
More to come!
Great tutorial thanks a lot!
You have some great instructions. Do you have instruction on the higher level aspects of PowerShell. I have written functions but did not know until I watched this video that I need to type (. ./filename) for my file to be recognized. What does that do?
Finally, I can start to make my vim-plug manager lol
I must know how you make your cursor blink in that style! Very pleasing compared to a flashing cursor
Saw that too and had to research. Add config "editor.cursorBlinking" to settings.json with options of 'blink', 'smooth', 'phase', 'expand' or 'solid'. 'Expand' is the one used in the video.
How many more videos in the series do you think are left? Also do your blog posts contain all the same info from the youtube vids?
That's a good question. Currently I'm aiming for 15 episodes, but that may end up changing. Let me know if there is something specific you'd like to see covered! Blog posts and videos are pretty similar. The goal was to provide the same content for both, so people could choose their preferred learning format.
Great tutorial but the difficulty spike of this from pws logic vid is massive.
right after the function ends.. why do you comment function name? At @25:30 , right after function definition ended, you commented on its name.. is there any advantage or just for clarity?
Great question.
When you start writing a lot more functions, and grouping functions together.
It can help to see when a function stops/starts.
So yes, I have gotten in the habit of including the function name in a comment at the end.
When you stare at 6,000+ lines of code it can help to see when a function stops!
