## Overview

This is a small browser-based expense tracker. Users record cash-in or cash-out entries with an amount, note, date, and time; the app keeps entries in memory, then renders transaction history and recalculates totals and balance. The README only identifies the live deployment, so the workflow and capabilities shown here are based on the sampled `main.js` and the repository’s HTML entry point; no persistent storage is evidenced.

Main entry points: [`main.js`](https://github.com/bear2305/mywebpro/blob/main/main.js) (Form handlers), [`index.html`](https://github.com/bear2305/mywebpro/blob/main/index.html) (Tracker interface)
