The `any` type in TypeScript is a dangerous "escape hatch" from the type system. Using `any` disables many type checking rules and is generally best used only as a last resort or when prototyping code. Despite your best intentions, the `any` type can sometimes leak into your codebase. Calling an `any`-typed value as a function creates a potential type safety hole and source of bugs in your codebase. This rule disallows calling any value that is typed as `any`. ## Examples ### ❌ 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`; ``` ## When Not To Use It If your codebase has many existing `any`s or areas of unsafe code, it may be difficult to enable this rule. It may be easier to skip the `no-unsafe-*` rules pending increasing type safety in unsafe areas of your project. You might consider using [ESLint disable comments](https://eslint.org/docs/latest/use/configure/rules#using-configuration-comments-1) for those specific situations instead of completely disabling this rule. ## Related To - [`no-explicit-any`](./no-explicit-any.md) - [`no-unsafe-argument`](./no-unsafe-argument.md) - [`no-unsafe-assignment`](./no-unsafe-assignment.md) - [`no-unsafe-member-access`](./no-unsafe-member-access.md) - [`no-unsafe-return`](./no-unsafe-return.md)
