no-unsafe-call

Disallows calling a value with type any.

Despite your best intentions, the any type can sometimes leak into your codebase. The arguments to, and return value of calling an any typed variable are not checked at all by TypeScript, so it creates a potential safety hole, and source of bugs in your codebase.
