`object-access` is a lightweight Node.js utility that lets you read, write, and delete deeply‑nested properties using dot‑notation strings or key arrays. It works as a safe alternative to the null‑propagation operator, automatically creating missing objects (or optionally forcing overwrites) and throwing helpful errors when trying to set a property on a non‑object value. Ideal for developers who need concise, reliable hierarchical object manipulation in JavaScript/Node projects.
