How can I use the type system?

As of recently you could add type annotations

local x: number = 10

However in what ways can this change the behavior of code? I tried the following but no error is raised

--!strict
local x: number = 10
x = "hello" -- Editor warning
print(x) -- Prints hello

Is there a way to enable type mismatches to raise errors, so that I could remove assert(typeof(x)=="number") and similar?

Type hints are for developers. The runtime completely ignores your hints.

You don’t really need to do type checking unless you’re dealing with remotes. In that case, try t.
