How to Manage Variables Configuration in a PowerShell Project

Three approaches to managing configuration variables in PowerShell projects are covered: using a configuration file (dot-sourced .ps1), environment variables via the env: drive, and script parameters. Each method's pros and cons are compared across security, portability, flexibility, and complexity. The author also shares a preferred approach using a custom key-value config file parsed with a Load-Config function that sets global variables, along with general best practices like using Pascal case naming and storing secrets in Windows Credential Manager or Azure Key Vault.
