Why Are JavaScript Promise Callbacks In The Microtask Queue? Have you ever wondered why JavaScript handles asynchronous tasks the way it does? In this informative video, we'll explain the reasoning behind the placement of promise callbacks in the microtask queue. We'll start by discussing what promises are and how they help manage asynchronous operations in web development. We'll then explore how JavaScript’s event loop prioritizes different types of tasks, ensuring your code runs smoothly and predictably. You'll learn why promise callbacks don’t execute immediately but are instead added to a specialized list called the microtask queue. We’ll also cover how this system helps maintain the flow of asynchronous code, making your applications more responsive. Additionally, we’ll explain how async functions with await work seamlessly within this setup, preventing delays and keeping your user interface responsive. Whether you're a beginner or an experienced developer, understanding this process is key to writing reliable JavaScript code.
