Types

You may see things like { string } or { [string]: number } and be rather confused, these are luau types (you can see how to read them by following that link).

If you don't know already, roblox uses a different version of Lua, which is called 'Luau'. Pilot.lua is the exact same language as Luau (but with some extra functions!).

These types are ways of saying how a value is formatted in a manner your LSP (the thing that gives you all the squiggles and autocompletion) can understand.
