Frequently Asked Questions (FAQ)

What is Node JS & why is it important for web applications?

NodeJs is an open source runtime environment that allows developers to run JS code on the server side. It's crucial for web development as it enables building fast and scalable applications using JavaScript, which was traditionally limited to browser interactions.

How does Node.js differ from other server-side technologies?

Unlike traditional server-side technologies, Node js is non-blocking and event-driven. This means it can handle multiple requests simultaneously without waiting for one request to finish before moving to the next, leading to improved performance and responsiveness.

Can I only build web servers with Node.js?

No, Node.js can be used for various purposes beyond web servers. It's versatile and can be employed to build web applications, APIs, real-time applications, command-line tools, desktop applications & more.

What are the core features of Node.js?

Node js comes with an array of core features, including asynchronous I/O operations, package management using npm (Node Package Manager), a rich ecosystem of libraries and frameworks, and the ability to create both server-side and client-side applications using JS.

How does Node.js handle asynchronous operations?

Node.js utilizes a non-blocking architecture, allowing it to execute asynchronous operations efficiently. It employs callbacks, Promises & async/await syntax to manage asynchronous tasks, preventing the server from becoming unresponsive during I/O operations.

Can I use popular front-end libraries like React or Vue.js with Node.js?

Absolutely! Node.js can be paired seamlessly with front-end libraries like React, VueJs, or Angular to create full-stack applications. This combination allows developers to build both server and client components using the same programming language.
