Build and manipulate trees.
Basically, I've implemented a lot of tree structures that are then serialized
into a database. Even if you're using a document database, you probably aren't going
to store the whole tree as a single document, but instead use links to point to a node's
parents. That's how it usually works: there's a parentId column in a table and that
references another table, or even the same table, with a foreign key.
Then, you – if you're loading the whole tree from the database – rework this structure into a nested tree that's easy to code with. This module is trying to make it easier to do that. It's what Placemark uses, currently, for Folder support.
This package is @placemarkio/tree
