Useful in type utilities, such as disallowing anys to be passed to a function.

Example​

import type {IsAny} from 'type-fest';

const typedObject = {a: 1, b: 2} as const;
const anyObject: any = {a: 1, b: 2};

function get<O extends (IsAny<O> extends true ? {} : Record<string, number>), K extends keyof O = keyof O>(obj: O, key: K) {
	return obj[key];
}

const typedA = get(typedObject, 'a');
//=> 1

const anyA = get(anyObject, 'a');
//=> any
