map-obj

A self-referencing array is rebuilt as nested arrays ending in an empty object. The original circular reference is lost. The equivalent self-reference on an object is preserved. Reproduction Expected: Keep the array self-reference intact, as the object-mapping path does for circular objects. Suggested fix: Register the actual mapped array in the shared reference cache before mapping its elements, and reuse that array on subsequent visits. Version: 6.0.0. Environment: Node.js v24.19.0.

Currently symbol properties are ignored. Is it possible to add the option to preserve and iterate over them? The filter-obj library currently has support for it using

I found that if you have a Blob instance or File instance within object which passed in and deep is true the function will go inside this objects. I guess it is not correct because Blob and File are js's special objects and this logic breaks them. If you add a simple check like !(value instanceof Blob) here that will fix this problem. I can create PR.
