PowerShell scripts are plain text files and have a PS1 extension.

You’ll notice that on line four, I assigned a default value to the $attemptcount parameter. The default will be overridden by any input parameter, but will be used if the script is run without that Best Programming Languages for Game Development parameter being specified.

On line one, I’m only specifying one of the parameters—$logfile will thus be empty, and $attemptcount will contain 5, its default.
