# no-unsafe-call

[Added in v0.1.4](https://github.com/web-infra-dev/rslint/releases/tag/v0.1.4)
## Configuration

| Preset                              | Configured Value |
| ----------------------------------- | ---------------- |
| ✅ ts.configs.recommendedTypeChecked | `"error"`        |
| ✅ ts.configs.strictTypeChecked      | `"error"`        |


```ts title=rslint.config.ts
import { defineConfig, ts } from '@rslint/core';

export default defineConfig([
  ts.configs.recommended,
  {
    rules: {
      '@typescript-eslint/no-unsafe-call': 'error',
    },
  },
]);
```

## Rule Details

Disallow calling a value with type `any`.

Calling an `any`-typed value as a function or constructor is unsafe since there is no guarantee that the value is actually callable. This rule also flags tagged template expressions and `new` expressions with `any`-typed callee values, as well as calling values typed as the `Function` type.

Examples of **incorrect** code for this rule:

```typescript
declare const anyVal: any;
anyVal();
anyVal.foo();
new anyVal();

declare const fn: Function;
fn();
```

Examples of **correct** code for this rule:

```typescript
declare const greet: (name: string) => void;
greet('world');

declare const Cls: new () => object;
new Cls();

declare const tag: (strings: TemplateStringsArray) => string;
tag`hello`;
```
