Async JavaScript Explained – Callbacks, Promises & Async/Await

🚀 Async JavaScript Explained – Callbacks, Promises & Async/Await JavaScript is single-threaded, meaning it executes one task at a time. But what happens when we need to fetch data from a server or handle user interactions without blocking execution? That’s where asynchronous JavaScript comes in! In this video, you'll learn how JavaScript handles async operations, why synchronous code can cause problems, and how callbacks, promises, and async/await solve these issues. 📌 What You’ll Learn in This Video: ✅ Why Synchronous JavaScript Can Cause Problems ✅ How Callbacks Work & Understanding Callback Hell ✅ What Are Promises & How They Fix Callbacks? ✅ Creating & Handling Promises in JavaScript ✅ then & catch Functions Explained with Examples ✅ Promise Chaining – Fixing Nested Callbacks ✅ Introduction to Async/Await – A Better Approach to Async Code ✅ Limitations of Async/Await & How to Handle Errors ✅ Running Multiple Async Tasks in Parallel with Promise.all & Promise.allSettled ✅ Best Practices for Writing Clean Async JavaScript By the end of this video, you’ll be comfortable working with async JavaScript and writing efficient, non-blocking code. ⏳ Video Timestamps: ⏩ 00:00 | Introduction – What is Asynchronous JavaScript? ⏩ 01:00 Demo of problem with synchronous JavaScript ⏩ 02:32 Synchronous programming issue explained ⏩ 03:00 Async task execution with callbacks ⏩ 04:40 More realistic callback example ⏩ 05:52 Callback hell explained ⏩ 08:00 Introduction to promises ⏩ 09:03 Async JavaScript with promises ⏩ 09:11 new keyword in javascript explained ⏩ 10:11 Creating and handling promises in code ⏩ 11:23 then and catch functions of promises explained ⏩ 13:05 Fixing callback hell with promises ⏩ 13:51 Promise chaining explained with code demo ⏩ 14:40 Introduction to Async/Await ⏩ 17:05 Limitation of using async await explained ⏩ 18:04 Parallel async task execution with Promise.all and Promise.allSettled ⏩ 20:32 Best practices with async JavaScript 🤔 Why Learn Asynchronous JavaScript? 🔹 Avoid UI Freezes & Improve Performance – Keep your apps responsive. 🔹 Handle API Calls Efficiently – Fetch data without blocking execution. 🔹 Write Clean, Maintainable Code – Move beyond nested callbacks. 🔹 Master Modern JavaScript – Async/Await is the standard for async programming. 📜 What’s Covered in This JavaScript Crash Course?
