How to implement linked lists in node.js?

Question

MongoDB

Hello. Not sure the title is correct. An example is adding products to an online store. First, we have the opportunity to specify several characteristics of the product. Depending on the given "characteristic-value" set, the characteristics available for editing change. The set of nested characteristics is large. Like a bloated version of "country-> region-> city". What is the name of this template (pattern) and are there implementation examples on node.js and mongodb?

In the context of relational databases, I would point to EAV, but it’s more difficult here, since mongodb implies database denormalization and work with data aggregations.
