// JavaScript demo of running Windows powershell scripts. This
// demo is based on lots of the previous scripts that were shared
// in the Momentum Discord channel.
// Improvements are:
// - Populating the USB drive with payloads.
// - PowerShell polling for the USB drive to be attached.
// - altPrint function to handle special characters (non-US keyboard).
// - PowerShell ejects the USB drive when done.
