assertEmptyObject()

import { assertEmptyObject, type ObjectKey } from '@dr.pogodin/react-utils';
                                       // or from '@dr.pogodin/js-utils';

function assertEmptyObject(object: Record<ObjectKey, never>): void;

Asserts the given object is empty, both at compile- and runtime. At compile-time the assertion is achieved via the argument's type definition, as the TypeScript compiler will forbid to pass in any argument that is not an empty object. At runtime this function throws an error if the given object has any key (as per Object.keys()).

Arguments​

  • object — Record<ObjectKey, never> — The object to assert.
