Okay, there are 2 things that I am getting for your questions. Classes, the property of instances, or Classes, as in wiki classes or tutorials.
Tutorials are a great way of getting started with scripting. On the wiki, they have made many tutorials ranging from newbie to expert. You can get started over here:
http://wiki.roblox.com/index.php?title=AllTutorials
Over here you can see all tutorials, from building to scripting to full game creation.
If you scroll down, you will find the scripting section I would begin at the Beginner section. they are arranged from the easiest to the hardest.
Another thing I would consider is looking at roblox cookbooks.
http://wiki.roblox.com/index.php?title=Cookbook
This is basically, well... a cookbook. I'm thinking of making pasta today, I'll reference the cookbook. I'm thinking of making a ChildAdded/RemoveEvent... I'll reference the cookbook.
Even asking someone in the community chat for a scripting challenge can improve your scripting, and like so, you can reference the cookbook for that too.

What are you asking?
What a class is.
"like functions in classes," reminds me of Java classes. Maybe he was referring to other programming languages to elaborate his point or something. Ask your said friend just to make sure.

If he's referring to that, then just don't worry about it.
