What Will I Learn?

• Learn some of the vital concepts of back-end engineering
• Get to a level capable of easily learning various NodeJS frameworks and libraries
• Truly and deeply understand what exactly NodeJS is and see its full potentials far beyond just creating web servers
• Understand and master NodeJS as it is without using any other NPM packages
• Understand some of the most important operating systems concepts that every back-end developer needs to understand
• Be able to easily learn and understand the NodeJS documentation
• Learn how to directly deal with binary data and manipulate the 0s and 1s however you want
• Learn the most important Networking concepts and understand where NodeJS exactly comes into play
• Learn exactly what happens when you deploy your back-end applications rather than focusing on a few tools
• Learn how to create low-level network applications directly on top of TCP or UDP and develop your own protocols
• Deeply understand what HTTP really is and how it works
• Get a deep understanding of the File System
• Master Streams to develop highly performant and memory-efficient applications capable of dealing with terabytes of data with ease
• Learn how to incorporate compression to enhance the speed of your network applications
• Understand Unix and open up a world of new possibilities
• Understand the EventEmitter object
• Master Multi-Threading in NodeJS & achieve significant performance improvements

Requirements

• At least one year of programming experience
• A good knowledge of JavaScript
• While not mandatory, a little bit of experience with ExpressJS and HTML could be helpful
• Not a strict requirement, but for the Multi-Threading section, it is recommended to be on a machine with a CPU that has at least 4 cores

Target audience

• Developers who are tired of jumping from one framework to another, tired of learning many different useless patterns, who want to step up their skills and get to an innovative point
• Self-taught software developers who haven't focused on computer science concepts
• NodeJS developers who still feel like they don't understand NodeJS even after using it for years
• Back-end developers aspiring to take things to the next level and lead change in the industry instead of following trends
• Developers who want to understand things at a much deeper level
• Computer science students eager to apply their academic knowledge in real-world scenarios
• Beginner and intermediate developers who want to learn how to make more informed and effective decisions in their learning journey for years ahead
