#Rule Details

Disallows the any type. Using the any type defeats the purpose of TypeScript's type system. When any is used, all compiler type checks around that value are ignored. This rule reports on explicit uses of the any keyword as a type annotation. It suggests using unknown for safe type assertions, never for generic type parameters that should not be used, and PropertyKey instead of keyof any.

Examples of incorrect code for this rule:

const age: any = 'seventeen';

function greet(): any {}

function foo(arg: any): void {}

const key: keyof any = 'name';

Examples of correct code for this rule:

const age: number = 17;

function greet(): string {
  return 'hello';
}

function foo(arg: unknown): void {}

const key: PropertyKey = 'name';
