From my experience indexing with ['step brother'] does work all the time. I think the PowerShell team took inspiration from other languages for that

Which VS Code plugin you use here to run the definite part of code?

Your video is nice but you seem not that well experienced with hashtables. Not very confident in your explanations.
For example, when you put the propriety inside brackets, you were surprised but it's a normal behavior. And when you talk about creating new properties, you say it's just preference and there is no difference between hashtable.property = value VS hashtable.add("key", "value"). There is a difference. If the property already exist, you are overwriting it by doing the first option but if you use the add() method, you can't overwrite properties.
Finally, later in the video, you seem to not understand how write-host is working...
But, I guess you're a nice guy nevertheless so have a good day aha
