This playlist is great! The speed you move through is a happy medium and you explain the concepts really effectively.

Thank you, I really appreciate your hard work!

I stumbled on your site the other day and have been going through the PS, while I use to use PS all the time when I was working in windows, I move over to Linux about 10 years ago. I have since been involved with Azure so back to PS again. A few things to complement you on.
1. You speak clearly and explain it very well.
2. Not too much joking around which is nice as well.
3. You provide good details on how to use the techniques.

4. You explain it so I feel anyway 99% of folks can understand it, which is important.
5. While there are a few other channels out there the hardest part for me is understanding what the person is saying, no offense to anyone from another country, but if struggle to understand what a person is saying it make it very difficult to learn it.
So, thank you I am enjoying you channel very much. I hope you will put some of what we are learning here into practice. Notice you were a System Administrator if you could maybe so some of your work and walk us through some of your scripts it might put things in perspective, just a thought. Thanks again.

These videos are fantastic. Thank you for putting in the work. They remind of my PR reviews with some of my favorite tech leads. Great stuff.

Hi: I am really enjoying your video series although I am only 4 videos in. I am new to PS and still learning about where it fits into the world. So, the one thing that I think would really make a huge difference is little more discussion about use cases. Sort of "Why do I want to learn this stuff?" I think this would provide more context around the material you are presenting.

Thank you for the videos. Very helpfull.

Concise and informative, a great job. Under membertype what is a property vs Event. Can you explain this further if possible.

[eduardomoura]

Great video series and explanation, congratulations!
For large key, value pairs (> 1000 pairs), which one is more efficient, HashTables or Custom Objects?
Thanks!

Its unbelievable difficult and annoying to follow your lessons with continuous youtube advertising.
You are a very good teacher by the way and I want to thank you for your efforts.

Love your videos, i am trying to work out how to retrive a value form a custom-object when there is more that one row, im working with an API that returns a custom object with for member types of NoteProperty ID, Label, Value and position, how do i query the customobject to look for a value in the label and return the corresponding value, your video only shows working with one entry in the custom object and i cannot work out how to filter to a particular entry

[FranLegon]

Great video, thank you! But damn, I really wanted you to explain how you can have multiple "rows" in a PsCustomObject. That is, multiple elements with the same properties (such as $employee1 and $employee2, which could have been appended into a single [PsCustomObject]$employees). This is great because you can index elements like in arrays

Showing how to load the hash table from a command like Get-ChildItem or from a text file would be powerful.

Hi, first i have to say thanks for your work ...
In PS Version 7.3.6 ContainsKey doesn't exist :-)

[No.u]

Why are you so obssesed with Strictversion ?

[pranavdeshpande]

Please create a video to use ArrayList vs Arrays Vs Hashtables to loop through Big Oracle Datasets, and how the performance works on using these different type of arrays, this would be more helpful to provide best realtime example.
