Functions allow us to modularize our scripts and reuse code over and over again. In some cases, you may want PowerShell to return information back to the parent scope so it can continue to be used. Below is a very simple function.
Function DoMath
{
$a = 5 + 5
}
DoMath
When we call this function, it returns our data. We can set it up to return the data to a variable by calling the function with this command:
$a = DoMath
The Return keyword is available. Return acts as a break for the function. It will return the data specified, and stop processing the rest of the function.
Function DoMath
{
$a = 5 + 5
}

Even though there is a Write-Host statement, the Return keyword prevents its execution.
