Falsy

type-alias stable

A simple type to represent a gamut of "falsy" values... with a notable exception: NaN is "falsy" however, it is not and cannot be typed via TypeScript. See comments here: https://github.com/microsoft/TypeScript/issues/28682#issuecomment-707142417

type Falsy = null | undefined | false | 0 | -0 | 0n | '';
