Project Overview

This project implements a pure JavaScript auto-complete widget for a text <input>, featuring:

No well-known UI libraries used – everything is built from scratch.
Dataset of 100~1000 entries – e.g., timezone names from tzdata.
Input validation – users can only submit if their input matches an entry in the dataset.
Works locally – can be loaded from http://localhost/ or file:/// without any server-side logic.
Efficient and memory-conscious – designed for performance and low resource usage.
Unit-testable and reusable code.
