Lodash Internal Object Types

This package, `lodash._objecttypes`, is an internal utility module extracted from Lo-Dash v2.4.1, released in December 2013. It provided the `objectTypes` variable, an internal structure used by Lo-Dash's core functions for type checking (e.g., `isObject`, `isPlainObject`). It was part of Lo-Dash's modularization strategy in its second major version, where internal components and methods were published as separate npm packages. However, this specific package is not intended for direct external consumption and its internal structure, existence, and API stability were never guaranteed. The main Lodash library has since evolved significantly, with the current stable version being 4.18.1 (as of April 2026), and its internal modularization and distribution methods (like `lodash-es` for ES modules) have changed considerably. This package is no longer maintained as a standalone entity and its functionality is integrated or superseded within modern Lodash versions. Its primary historical differentiator was serving as a foundational internal piece of the Lodash v2 type-checking mechanism.
