PowerShell Splatting
Introduction
Splatting is a method of passing multiple parameters to a command as a single unit. This is done by storing the parameters and their values as key-value pairs in a hashtable and splatting it to a cmdlet using the splatting operator @.
Splatting can make a command more readable and allows you to reuse parameters in mulitple command calls.
Remarks
Note: The Array expression operator or @() have very different behavior than the Splatting operator @.
