In today’s episode, Mathias tells us how he ended up with the name IISResetme. We then get a great explanation of the Abstract Syntax Tree (AST). Jordan learns he needs to do much more reading on this subject but appreciates this awesome head start to learning. We then talk about how PSProfiler injects code into the AST to measure your scripts to help you find ways to speed up the runtimes.

Community isn’t just what I do. It’s where I get my energy. I genuinely light up when I see someone land a new job, level up a skill, or show up to their first conference. I love sharing that passion with others.
