Alt: Just throwing this little bit of code out there before I throw it away.
This has been possible in PowerShell forever.
Maybe I'm Javascripting wrong, but I was not able to do this sort of template inception in JS. Don't know of too many other languages where these sorts of shennanigans work, either.
Add it to the list of fairly unique things about PowerShell.

RegEx and LDAP Filters are two great use cases for joining arrays of strings in PowerShell. Been building RegEx that way for a while, but did it with LDAP Filters today and found it quite nice!

Good news for #webdev and #PowerShell people:
I've created a little educational module "Servers101"
github.com/PowerShellWe...
It's a collection of simple servers written in pure PowerShell.
Hopefully this helps everyone see how simple servers can be.

#PowerShell does pretty great as a meta shell language.
Also, it's strings are designed to avoid this exact situation.
There are 4 string types in PowerShell
- Single quote 'Like this'
- Double quote "Can have $variables"
- Single heredoc @'
I don't need to escape
'@
- Double heredoc @"
"$pid"
"@

The other day I made a 101 line file server as a demo.
I carefully kept each line within 80 characters.
Where in the wide world of #PowerShell docs could such an example go?
Inquiring minds want to know 😉.

If people are helpful, you've got a good community.
If people are hurtful, you've got a bad community.

Alt: Walter White might be evil, but he never sent a thank you message to the current administration to millions of people who didn't want it.
That's my best guess as to why TikTok sharing on At Protocol / BlueSky is so low.
It's legitimately embarrassing though.
If I had run this same experiment two years ago I expect I'd get vastly different numbers.
