Lodash Internal BaseCopy

lodash._basecopy is an internal Lodash module, specifically version 3.0.1, published over a decade ago in April 2015. It exposes the `baseCopy` function, which is a core utility used internally by Lodash for copying object properties. This package is part of the older Lodash v3 ecosystem, which predates the significant breaking changes and modularization introduced in Lodash v4. While Lodash itself (currently v4.18.1) is actively maintained with a regular release cadence addressing bugs and security, `lodash._basecopy` is effectively abandoned as a standalone, directly consumable package. Modern Lodash encourages direct function imports from `lodash` or `lodash-es` rather than using these older, internal micro-modules, many of which are slated for removal in Lodash v5.
