How to differentiate between microtasks and macrotasks in JavaScript

Task scheduling in web applications plays a crucial role in managing user interactions and response times. Proper handling of asynchronous operations prevents delays during events like clicks. Techniques such as using `await` within event handlers and `requestAnimationFrame` for updates ensure a responsive UI. Understanding microtasks and macrotasks is essential to avoid performance issues and unexpected behaviors.

How to debug asynchronous behavior in JavaScript

Effective techniques for tracing promises and callbacks include utilizing browser debugging tools and setting breakpoints. The `.finally()` method aids in executing cleanup code after promise resolution. Custom logging functions enhance context, while `Promise.all()` tracks multiple asynchronous operations. These strategies improve debugging and optimize performance.

How to detect blocking operations in JavaScript

Identifying blocking behavior in applications is crucial for performance. Utilize Node.js profiling tools like `--inspect` and Chrome DevTools to visualize the event loop. Techniques include logging execution times, processing tasks in chunks with `setImmediate`, and using worker threads for parallel execution. Optimize applications for responsiveness and efficiency.
