|
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.
|
|
|
|
## Rule Details
|
|
|
|
This rule disallows calling any variable that is typed as `any`.
