NodeJS Unleashed: From Basics to Brilliance, NodeJS Architecture, Async Programming, Modularization, and More

Dive deep into the world of NodeJS with this comprehensive course designed to take you from the basics to advanced concepts. Whether you're a beginner or looking to refine your skills, this course will provide you with a solid understanding of JavaScript fundamentals and their application in NodeJS.

We begin by exploring JavaScript engines, covering syntax parsing, compilation, memory handling, and garbage collection. You’ll learn about the differences between single-threaded and multi-threaded processes and get an introduction to the V8 engine, which powers NodeJS. Understanding the runtime environment and external APIs is crucial, and we will differentiate between JavaScript engines and runtime, emphasizing the concept of binding.

Next, we delve into NodeJS architecture and its compatibility with node green. We will cover callbacks and their role in asynchronous programming, addressing common issues like callback hell and providing strategies to overcome them. You'll become proficient in using Promises, including the Promise API, and mastering sequential and concurrent execution. Async/Await will be introduced for cleaner asynchronous code, along with try..catch and limited parallel execution patterns.

You'll also learn about async handling methods in NodeJS, understanding the Worker Pool, and handling I/O operations asynchronously. We'll compare blocking and non-blocking I/O in NodeJS, understand core modularization, and explore the necessity of separating files into modules. You'll get an in-depth look at ES6 and CommonJS modules, handling Intellisense limitations with `require` syntax, and explaining relative and absolute paths.

Moreover, this course covers core modules, third-party modules, local files, and lazy importing in NodeJS. You’ll gain practical knowledge of the File System (fs) Module in NodeJS, including writing files synchronously without overwriting. We will also compare NodeJS with browser runtimes like ReactJS and introduce you to external JS packages. Finally, you'll learn to configure ESLint for NodeJS projects, ensuring your code is clean and maintainable.

Join us and unlock the full potential of NodeJS, equipping yourself with the skills needed to build efficient, scalable, and maintainable applications.
