How the Javascript Event Loop Manages Asynchronous Code Execution
Article Introduction：JavaScript's event loop coordinates asynchronous operations through macro tasks and micro tasks. Synchronous code is executed first, asynchronous tasks are processed by the browser and then called back to queue. Microtasks (such as Promise) are preferred over macrotasks (such as setTimeout). Each event loop first handles one macrotask, and then clears all microtasks to ensure that microtasks respond in a timely manner. Reasonable task order can avoid blocking the main thread and improving performance.

The Node.js Event Loop: A Developer's Guide to Concepts & Code
Article Introduction：Asynchronous programming of Node.js: In-depth understanding of event loops
Asynchronous programming is extremely challenging in any programming language. Concepts such as concurrency, parallelism and deadlock make even the most experienced engineers tricky. Asynchronously executed code is difficult to predict and difficult to track when there is a bug. However, this problem is inevitable, because modern computing has multi-core processors. Each CPU core has its own thermal limit, and the single-core performance improvement has reached a bottleneck. This prompts developers to write efficient code and make full use of hardware resources.
JavaScript is single-threaded, but does this limit Node.js' ability to take advantage of modern architectures? One of the biggest challenges is dealing with the inherent complexity of multithreading. Create new threads and manage threads between
