Tip 5:
Try a container! As a followup on tip 4, you can also try (and of course even run in production) PowerShell (and PowerCLI) in a container with for example Docker! This allows you to investigate if PowerShell is something for you. If you're a long time PowerCLI user, grab that container too!
Links:
Official PowerShell container: https://hub.docker.com/_/microsoft-powershelldocker pull mcr.microsoft.com/powershell
Official PowerCLI container: https://hub.docker.com/r/vmware/powerclicore/docker pull vmware/powerclicore
Both are official containers and well maintained.
Tip 6:
Use a proper IDE! A good IDE (Integrated Development Environment) is essential to your day-to-day scripting and development. And my favorite at this moment is Visual Studio Code (https://code.visualstudio.com/). It's free, fast, actively maintained, platform-independent, fully extensible using marketplace with loads of extensions, fully customizable, full git support, powerful debugging capabilities, and code highlighting plus formatting through IntelliSense. Oh, and did I say it is free!!!! Yeah, all that for free - I can highly recommend it!
And once you downloaded and installed VSCode, ensure you get the Powershell extension next (https://github.com/PowerShell/vscode-powershell).
And while you're checking that out, also grab the docker extension (https://github.com/microsoft/vscode-docker). This extension allows you to easy build, manage and deploy containerized application. To get an idea on how it looks like, check out the screenshot below.
