Lodash is a popular utility library that provides a wide range of functions for manipulating arrays, objects, and other data types. It includes methods like _.clone and _.cloneDeep, which offer similar functionality to object-copy for shallow and deep copying of objects. Lodash is more comprehensive and widely used for various utility functions beyond just object copying.
rfdc (Really Fast Deep Clone) is a specialized package for deep cloning objects. It is known for its performance and efficiency in deep copying objects without the overhead of additional features. Compared to object-copy, rfdc focuses solely on deep cloning, making it a lightweight alternative for this specific task.
Deepmerge is a library designed to merge objects, but it can also be used to clone objects by merging an object with an empty one. It provides deep merging capabilities, which can be useful for combining configurations or state objects. While not specifically a cloning library, it offers similar functionality in terms of deep copying through merging.
