This module delves into the fundamentals of module systems in Node.js, covering ES modules, CommonJS, and the revealing module pattern. Learners will explore module resolution, dependency management, and interoperability between different module systems, including considerations for TypeScript projects. By the end, you'll understand how to organize, import, and export code efficiently while handling advanced scenarios like circular dependencies.

This module delves into the use of callbacks and the Observer pattern in Node.js, highlighting both synchronous and asynchronous programming techniques. Learners will discover best practices for designing APIs, handling errors, and combining callbacks with events to build robust, reactive applications.

This module delves into asynchronous programming in Node.js, focusing on callback patterns and control flow techniques. Learners will tackle common challenges such as callback hell, and explore sequential, concurrent, and limited concurrent execution using practical examples like a web spider application. By the end, you'll be able to manage complex asynchronous tasks efficiently and write more maintainable code.

This module introduces the concepts and practical applications of promises and async/await for managing asynchronous operations in Node.js. Learners will explore sequential and concurrent execution patterns, error handling strategies, and common pitfalls in asynchronous programming. By the end, you'll be able to write cleaner, more efficient asynchronous code using modern JavaScript techniques.
