regexp-clone

The main difference is in the implementation and possibly in the specific features or options provided by each package.

The clone package is a more general utility for cloning objects, arrays, dates, and regular expressions in JavaScript. While it can clone regular expressions like clone-regexp, it is not specialized for regex cloning and does not provide options to modify the cloned regex's properties.
