RegEx Beginner Tutorial - Boundaries & Whitespaces
Boundaries in regular expressions check for positions while whitespaces include the space character, newlines, carriage returns, horizontal tab, etc.
They are matched similarly when using regular expressions in C#, JavaScript, Java, or Python.
This regex beginner tutorial shows you how to match boundaries and how to match whitespace characters. It's also the last one in the series, so I hope you enjoyed it!
I'd recommend practicing your regex skills on a coding challenges platform to improve and see how others approach them. The following video should help you choose which coding platform is best for you.

RegEx Beginner Tutorial - Groups & Backreferences

Groups in regular expressions come in two forms - capturing groups and non-capturing groups. Capturing groups work together with backreferences to reference saved matches.

Disjunctions are often used with groups to mat...

      I've never had any reason to run code inside a terminal - unless maybe you mean scripts to build an app or run tests, then those can be run in an internal terminal. If you're just trying to open the Visual Studio terminal, press Ctrl + ` or go to the View tab (on the menu bar at the top of your screen in Visual Studio) -> Terminal.

    Depends if your GPU/monitor activates as fast as that post screen stays up. My 4090 and predator 4k monitor don't initialize until the windows loading screen is already up.

Was curious so I did a quick test on with a intel 9700k B360 system, dropped in a 1660 Super I see about 4~5 seconds average of viewable post screen, I then put in a 3080 and it's up for 3 seconds, not a ton different but even without timer is noticeable. My 4090 is on liquid so it's not really one I can pop out fast to try it.
