Node.js Basics

Node.js Basics is an extensive learning repository covering Node.js programming, server development, APIs, and common interview topics. Its material addresses event-driven programming, callbacks, callback hell, asynchronous behavior, commands, APIs, programming exercises, and frequently asked questions. Separate reference files collect multiple-choice questions, data-structure material, design-pattern notes, and practical Node.js examples. The repository also contains sample projects for MySQL integration and several JWT authentication approaches. REST API development is a recurring theme throughout the collection. Most of the repository is written in JavaScript and is organized as a self-study reference rather than a single application. The current repository describes its content around Node.js 24.x and continues to function as a broad study and interview-preparation resource.
