FAQs on Node js tutorial step by step 5 this Video Lecture - The Complete NodeJS Developer Course (in Hindi) - Back-End Programming

1. What is Node.js?
Ans. Node.js is an open-source, server-side runtime environment built on Chrome's V8 JavaScript engine. It allows developers to run JavaScript code on the server, enabling them to build scalable and high-performance web applications.
2. How is Node.js different from traditional server-side languages like PHP or Java?
Ans. Unlike traditional server-side languages, Node.js uses a non-blocking, event-driven I/O model, which makes it highly efficient and suitable for handling a large number of concurrent requests. It also allows developers to use JavaScript both on the client and server-side, making it easier to build full-stack applications.
3. What are the advantages of using Node.js for back-end programming?
Ans. Some advantages of using Node.js for back-end programming include its ability to handle concurrent requests efficiently, its lightweight and scalable nature, its extensive package ecosystem (npm), and its seamless integration with front-end JavaScript frameworks. Additionally, Node.js allows developers to write server-side code using the same language as the client-side, simplifying the development process.
4. Can Node.js be used for building real-time applications?
Ans. Yes, Node.js is well-suited for building real-time applications. It provides features like event-driven architecture and websockets that enable real-time communication between the server and the client. This makes it an ideal choice for applications like chat systems, collaborative tools, gaming platforms, and live streaming applications.
5. What are some popular frameworks and libraries used with Node.js?
Ans. Some popular frameworks and libraries used with Node.js include Express.js, Nest.js, Hapi.js, Koa.js, and Meteor.js. These frameworks provide a structured approach to building web applications, handle routing, middleware, and provide numerous plugins and extensions to enhance the development process.
