Nodejs Development

This one covers the fundamentals you actually need for Node.js work: event loop mechanics, async patterns from callbacks through async/await, streams, file system operations, and HTTP server basics. It's pitched at developers who understand JavaScript but need to internalize Node's quirks, like why process.nextTick runs before setTimeout or how to avoid blocking the event loop with heavy computation. The examples show CommonJS and ES modules side by side, which is helpful since you'll encounter both in real codebases. Good for building APIs, CLI tools, or microservices where you need to handle async operations correctly without creating callback hell or mysterious performance issues.
