## Overview

This repository is a set of independent programming exercises, not one deployed application. Its examples demonstrate JavaScript language features, asynchronous work, data manipulation, and student-data HTTP servers. The clearest user-to-result workflow is an HTTP request routed to a controller, which reads and summarizes CSV data before responding. Other exercises are standalone demonstrations; the graph preserves the documented modules without implying they form a single pipeline. Connections are limited to excerpted calls and imports; unsampled exercise behavior is summarized only at its directory path.
