vilicvane/replace-object

replace-object is a utility for in-place object replacing that allows developers to update an object's properties by merging in a new object, with options to control whether to add new properties, delete missing ones, or perform shallow replacement. It's designed for JavaScript/TypeScript developers who need to efficiently update objects without creating new ones, and includes special support for MobX observable objects. The library is particularly useful for state management and data manipulation tasks where in-place updates are preferred over creating new object instances.
