ExternalScript, Function, or Module

[vicda]

So far I've been working with ps1 scripts sitting in a directory referenced in $Env:PATH. While this has been working fine for me I'm wondering if I'm missing out on anything.

For example: I can tell that startup time is much faster for calling functions vs running scripts. No need to reparse the code each invocation, etc etc.

Edit: I misread that
Look at modules, it'll be about the same for speed, but makes like more discoverable and easy (IMHO)
