Classification of Node.js: Backend vs. Frontend

Node.js is a server-side Running JavaScript runtime environment, mainly used for back-end development. The following are two reasons why Node.js is classified as a back-end technology:

1. Runs on the server side

Node.js mainly runs on the server, rather than in the client's browser. It supports web applications by interacting with databases, handling requests, generating responses, and performing other server-side tasks.

2. Asynchronous and non-blocking

Node.js adopts an asynchronous and non-blocking I/O model, making it very suitable for handling frequent requests, such as web servers . This allows Node.js to serve other requests while waiting for an I/O operation (for example, reading a file or a network request).
