Questions about Luau

So, I am developer for a game and my team is coding using Luau type checking.

I already did a print test on a living game which basically consists of this:

local function a(b: number) => number
    return b^b

Well, it printed fine but I still wanna ask this just to be secure about it… can I use Luau type check on living games?

It is still in beta, so no. Roblox engineers have yet to announce that it is safe to use.
