Asynchronous JavaScript

JavaScript is single-threaded, but that doesn't mean it can't handle multiple operations. Learn how to write non-blocking code that keeps your applications fast and responsive.

---

Core Concepts

• Promises - The foundation of async JavaScript
• Async/Await - Modern syntax for handling promises
• The Event Loop - How JavaScript handles concurrent operations

Practical Applications

• Fetch API - Making HTTP requests
• Error Handling - Managing async errors gracefully

---

Learning Path

1. Start with Promises - understand the callback pattern and why promises were created
2. Learn Async/Await - the modern way to write async code
3. Deep dive into The Event Loop - understand how JavaScript actually works
4. Apply your knowledge with Fetch API - make real API calls
5. Master Error Handling - build robust applications

Prerequisites

Before diving into async JavaScript, make sure you understand:

• Functions
• Closures
• The this Keyword

Next Steps

• REST APIs - Design and consume RESTful services
• Full-Stack Development - Build complete applications
