JavaScript Event Loop Visualizer is an interactive tool that helps developers understand how the JavaScript Event Loop works. It visually demonstrates how the Call Stack, Callback Queue, and Web APIs interact to execute synchronous and asynchronous code.
This project is designed for beginners and developers who want to clearly understand JavaScript execution flow.
Understanding the JavaScript Event Loop can be confusing. This project provides a visual simulation to help users learn:
- How JavaScript executes code
- How async operations work
- How the call stack behaves
- How callbacks are handled
- Execution order of synchronous vs asynchronous tasks
✅ Call Stack visualization
✅ Callback Queue simulation
✅ Async and sync task handling
✅ Real-time execution flow
✅ Interactive user interface
✅ Step-by-step execution tracking
✅ Beginner-friendly design
The visualizer simulates:
- Call Stack → Executes functions
- Web APIs → Handles async operations (setTimeout, fetch, etc.)
- Callback Queue → Stores completed async tasks
- Event Loop → Moves tasks to call stack when ready
Users can add tasks and observe how JavaScript processes them.
- JavaScript (ES6+)
- HTML5
- CSS3
- Browser APIs
