I hope this helped

Well scripting consists of hundreds, if not thousands of subcategories so to be honest, it would be hard to post this answer and all of a sudden you're as good a Scripter as someone who hasn't been scripting for 10 years. I advise you watch Peasfactory on YouTube and learn from him. He teaches you the basics through to the advanced end of stuff. You just put these together and you get something much more than a basic "click to turn invisible" script. Good luck on your scripting journey —Commag

Firstly some youtube channels that use scripting ...:
ROBLOX -scroll down to see tutorials
AlvinBlox
SpooksHD
Peas Factory
The RPG makers
There are many more but I'm not going to list them all...
The Second option is Roblox Wiki...
Cookbook
Scripting
Intro To Scripting
All Tuturiols
I recommend you start with easy and work your way to hard.
Searching up stuff with roblox wiki...
Some things may have 1 or 2 scripts attatched to them so you know what it does, an example of this: findfirstchild
Some may come with Properties,Functions,Events, e.g: Replicated Storage
Some may come in big long lists... eg: math
