Mastering Node.js: Event Loop, Non-blocking I/O, and Asynchronous Programming

Node.js Overview:
Node.js is a platform built on Chrome’s JavaScript runtime, designed for building fast and scalable network applications.
It uses a non-blocking, event-driven I/O model, making it efficient for handling I/O-intensive tasks.
Event Loop and Non-blocking I/O:
Node.js utilizes a single-threaded event loop to manage multiple concurrent operations.
Non-blocking I/O allows the process to handle other tasks while waiting for operations like disk reads or network requests, enhancing performance.
JavaScript Programming Concepts:
Emphasizes the use of single-purpose modules and functional programming.
Understanding JavaScript's scope, closures, and prototypal inheritance is crucial for efficient Node.js programming.
Uses async functions and callback patterns to manage non-blocking operations effectively.
Event Emitters and Streams:
Event emitters handle asynchronous events, such as user inputs or data streams.
Streams are used for processing data efficiently, especially for large files or continuous data flows.
Practical Examples and Libraries:
Examples include creating TCP and HTTP servers with minimal code.
Discusses practical uses of Node.js APIs, like fs.readFile, and the importance of non-blocking patterns.
Libraries like async help manage complex asynchronous workflows.
