This article analyzes performance benchmarks for Node.js versions 16 through 25, highlighting significant improvements, especially in version 25. It covers various tests including HTTP throughput, JSON parsing, and numeric operations to illustrate the evolution of Node's performance over time.

Worker Threads in Node.js enable true multithreading by allowing JavaScript code to run in parallel, which is essential for handling CPU-intensive tasks without blocking the main event loop. This guide covers the implementation, use cases, communication methods, and best practices for using worker threads effectively in production applications. It also emphasizes the importance of security and performance considerations when utilizing this feature.
