Why do variables = brackets?

Why do variables sometime equall to brackets?

Example: "local hello = ()

Why would you wanna use it

You mean this?

local hello = {}

These are tables and you use them to store multiple values.

If it’s local hello = (), then it’s a pair value, but if it’s local hello = {} then it’s an array, a Roblox array can contain different types of data types, variables, and a bunch of stuff. It’s good for storing a lot of data, and a lot of other stuff, too. Take a look at this link and it should help you with tables.
