A set of utility types for TypeScript

/**

 *
 * `NaN` is also `Falsy`, but TypeScript doesn't have a numeric literal.
 * {@link https://github.com/Microsoft/TypeScript/issues/15135}
 *
 * `HTMLAllCollection` is also `Falsy`, but it's a deprecated feature.
 *
 * Also, `!!HTMLAllCollection` is inferred as true in TypeScript.
