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.

The article delves into the inner workings of Node.js, explaining its event-driven architecture and non-blocking I/O model. It highlights how Node.js handles asynchronous operations, enabling high scalability for web applications. Additionally, it discusses the role of the V8 engine in executing JavaScript code efficiently.

A quiz tests your knowledge of JavaScript's Date class through a series of questions, all verified with NodeJS 24.4.0 on a MacBook Pro operating in the BST timezone. The quiz aims to enhance understanding of date manipulation and formatting in JavaScript.

A machine learning framework for Node.js, called node-mlx, is introduced, which offers support for various platforms and includes features for training models, handling embeddings, and implementing large language models. It provides JavaScript APIs that mirror Python's MLX, with some limitations and differences due to JavaScript's characteristics. The project is still in development, providing opportunities for contributions and sponsorship.
