## What it is
An interactive React web application that visualizes JavaScript's Event Loop, showing how tasks, microtasks, and callbacks execute. It is the client for a companion backend service and is hosted at jsv9000.app.

## Use cases
- visualize javascript event loop
- understand microtask vs macrotask execution order
- learn how async javascript works
- teach event loop concepts to students
- debug setTimeout and promise ordering intuition

## When to choose
- you want an interactive, visual way to learn or teach the JavaScript event loop
- you need a demo tool to explain async execution ordering

## When to avoid
- you need a production debugging or profiling tool for real applications
- you need a maintained project with a license or active development
