JavaScript Fundamentals: While Node.js focuses on server-side development, you'll still need a strong foundation in JavaScript, including concepts like variables, data types, functions, and control flow.

Asynchronous JavaScript: You'll learn how to work with asynchronous JavaScript, understanding callbacks, promises, and async/await, which are crucial for handling non-blocking I/O operations.

Node.js Basics: You'll gain an understanding of the Node.js runtime environment, how to install it, and how to run JavaScript code on the server. You'll also explore the Node.js event loop, which is central to its non-blocking nature.

Core Modules: Node.js provides a set of built-in modules for tasks like file system operations, network communication, and data manipulation.

npm (Node Package Manager): You'll get familiar with npm, the package manager for Node.js, which allows you to install, manage, and publish third-party packages and libraries.

Working with Databases: You'll learn how to interact with databases in Node.js. This can include using database libraries like MongoDB / MySQL, or connecting to databases through Object-Relational Mapping (ORM) tools like.

Error Handling and Debugging: You'll gain knowledge on how to handle errors gracefully and debug Node.js applications effectively.
