Hello,
This question applies to all programming not just Power shell. Besides reducing the number of lines in a code if you’re entering the same code more than once, is there any other benefits to using functions?
For example, does it make the program any faster? Any other advantages / Disadvantages?
Thank you,
Tony
A couple that immediately come to mind.
Re-usability. A function can be like a tool you’ve built and tested. You copy it out of one script and put it in another.
Readability. Sometimes you need a large block of code to perform a seemingly simple action. By creating a function with meaningful name, you can make your code easier to follow.
I’d also add that if your code is created as Advanced functions it can be packaged as a module
