# `no-unsafe-call`

Disallows calling an any type value.

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`.

Examples of code for this rule:

<!--tabs-->

### ❌ Incorrect

```ts
declare const anyVar: any;
declare const nestedAny: { prop: any };

anyVar();
anyVar.a.b();

nestedAny.prop();
nestedAny.prop['a']();

new anyVar();
new nestedAny.prop();

anyVar`foo`;
nestedAny.prop`foo`;
```

### ✅ Correct

```ts
declare const typedVar: () => void;
declare const typedNested: { prop: { a: () => void } };

typedVar();
typedNested.prop.a();

(() => {})();

new Map();

String.raw`foo`;
```

## Options

```jsonc
// .eslintrc.json
{
  "rules": {
    "@typescript-eslint/no-unsafe-call": "error"
  }
}
```

This rule is not configurable.
