PS tools and good habits.

Hi. I’ve been writing PowerShell scripts for my Team/company for half a year now and I’ve learnt quite a lot and some of my scripts are 100s of lines long and getting complicated. My tech lead has asked me to update a large script this week (again). I massively enjoy this and dive back in happily.

My question is what tools do people use to help them with their scripting, including tools for memory and lines of code you use regularly, to speed things up? With such a large script, I do use comments and examples accordingly. Any secret tips I may have missed?
