 This module uses an expanded set of type names that make no distinction between primitive values and objects. 
 For example, `5` and `new Number(5)` are both of type "number".
 
-| Type Name             | Values
-| - | -
-| array                 | `Array` objects
-| bigint                | _bigint_ primitives
-| boolean               | `false`, `true`, `Boolean` objects
-| date                  | `Date` objects
-| error                 | `Error` objects
-| function              | `Function` objects
-| map                   | `Map` objects
-| nan                   | `NaN`, `Number` objects with value `NaN`
-| null                  | `null`
-| number                | _number_ primitives, `Number` objects; excludes `NaN` values
-| object                | instances of `Object` that don't match another type in this list
-| promise               | `Promise` objects
-| regex                 | `RegExp` objects
-| set                   | `Set` objects
-| string                | _string_ primitives, `String` objects
-| symbol                | _symbol_ primitives
-| undefined             | `undefined`
-| weakmap               | `WeakMap` objects
-| weakset               | `WeakSet` objects
