The “Learn and Understand NodeJS” course by Anthony Alicea on Udemy is an excellent choice for those who want to gain a deep understanding of how Node.js works under the hood and how to make the most of it in application development.

Unlike other courses that only teach how to use Node.js, this one focuses on understanding its architecture and core concepts, such as the event loop, non-blocking I/O model, buffers and streams, built-in modules, and how they interact with the operating system.

Anthony Alicea is known for his ability to break down complex topics into clear and structured explanations, making this course ideal for developers who want to go beyond just using Node.js and actually master it.

You’ll also learn to build applications with Express.js, work with databases like MongoDB, manage REST APIs, and deploy projects to production.

If you want to go from just writing Node.js code to fully understanding its inner workings, this is the perfect course for you.
