Functions in PowerShell

 Functions in PowerShell

Functions are used to encapsulate code and reuse it throughout a script or module. They are declared using the function keyword followed by the function name and parameters. Here's an example:

function Get-Greeting {

    param($name)

    return "Hello, $name!"

}

$greeting = Get-Greeting -name "John"

Write-Host $greeting

In this example, we define a function called Get-Greeting that takes a parameter called $name and returns a greeting message. We then call the function and store the result in the $greeting variable.
