Quick question on Lua...

What are semicolons used for in Lua? I’ve noticed that in some code semicolons [ ; ] are at the ends of lines… are they there for a reason? If so, what is it? just wondering

They have no effect, in other languages they are required, like in PHP, so if you are used to PHP you can do it in LUA without affecting it.
I think it looks better and it shows where the code ends, better structure and readability.
