What is NodeJS and what is it used for?

NodeJS is a JavaScript runtime used to build fast server-side applications, APIs, real-time services, and backend tools.

Is NodeJS suitable for beginners?

Yes. Beginners can learn NodeJS by starting with JavaScript basics, modules, file handling, HTTP servers, and simple APIs.

What will I learn in a complete NodeJS course?

A complete course typically covers asynchronous programming, Express, databases, authentication, error handling, testing, deployment, and API development.

How do I build a REST API with NodeJS?

You can build a REST API using NodeJS and a framework such as Express to create routes, process requests, validate data, and return JSON responses.

What is the difference between REST APIs and GraphQL in NodeJS?

REST uses multiple endpoint-based routes, while GraphQL commonly uses one endpoint where clients request the exact data they need.

Can I create APIs in NodeJS from basic to advanced levels?

Yes. Start with simple CRUD endpoints, then add databases, authentication, authorization, validation, pagination, documentation, and security.

How can NodeJS be used with Generative AI?

NodeJS can connect applications to generative AI APIs, manage prompts and responses, stream generated content, and build AI-powered backend services.
