In Lua, variables can be either local or global, and their scope determines where they can be accessed.
If before variable is local - means variable is local, if before variable is nothing it means variable is global.

Here is a pretty good summary about lua.

But you also can use chatGPT to improve your coding and ask some questions about code.
