• Java Spring is more mature and has a larger community, but Node.js is easier to learn and use

Help & Support

What is Node.js?

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that executes JavaScript code outside a web browser.

What are the advantages of using Node.js?

Some of the advantages of using Node.js include its ability to handle large volumes of data, its ability to handle multiple requests simultaneously, its fast processing speed, and its ability to run on multiple platforms.

What is npm?

npm (Node Package Manager) is a package manager for the Node.js platform that allows developers to easily install, share, and manage packages or modules of code written in JavaScript.

What is the difference between Node.js and JavaScript?

JavaScript is a programming language that is used to create interactive effects within web browsers, while Node.js is a runtime environment that allows developers to run JavaScript code outside of a web browser and build server-side applications.

What is the event-driven architecture in Node.js?

Node.js is built on an event-driven architecture, which means that it uses an event loop to handle multiple requests simultaneously and efficiently. This allows Node.js to handle large volumes of data and requests without slowing down or crashing.

What is the role of callbacks in Node.js?

Callbacks are functions that are passed as arguments to other functions in Node.js. They are used to handle asynchronous operations and ensure that code is executed in the correct order.

What are the popular frameworks used in Node.js?

Some of the popular frameworks used in Node.js include Express.js, Koa.js, Hapi.js, and Nest.js.

What is the difference between Node.js and PHP?

Node.js is a runtime environment for executing JavaScript code, while PHP is a server-side scripting language. Node.js is event-driven and non-blocking, while PHP is blocking and typically used in a synchronous manner.
