## Overview
This repository is a collection of independent Node.js learning exercises, not one integrated application. Its examples cover fundamentals, asynchronous geocoding/weather lookups, Express servers, MongoDB-backed Todo APIs, a small rendered Todo app, and JWT login. The graph keeps those exercise branches separate; the README identifies the learning sources but does not document a unified user workflow. Edges are limited to relationships visible in excerpts or the source index; several listed exercises were not sampled.
